Overview Field 5 Flow (table entry) Source (table) Source (note)

45. Group of knots extending south from the candidate driving source (a red, nebulous star north of 5-4 A/B); uncertain. 5-4 may also belong to the northern lobe of a large flow from the L1641-N cluster. The flow position refers to the candidate driving source.

Overview Field 5 Flow (table entry) Source (table) Source (note)

49. L1641-N giant flow (Stanke et al. 1998; 2000). Only a small fraction of the northern lobe of the flow is detected in H₂ (5-14 B, G, P (?), 5-8), but this lobe is traced by optical HH-objects over a length of more than 6 pc (Reipurth et al. 1998, Mader et al. 1999). The southern lobe detected in the infrared extends over 4 pc (but may continue further south, beyond the edge of the mosaic 6). The length given in the table is measured over the H₂ features only, from 5-8 down to 6-16. Some other H₂ features north of the L1641-N cluster (5-1 and 5-4) may also belong to this flow. The H₂ features line out a rather broad path, but still the flow appears to be rather well collimated (the underlying flow is presumably also narrower than the path seen in H₂, since the H₂ features probably are bowshocks which are much wider than the flow). The path also appears to show some bendings, indicating time variable direction of ejection. The flow position refers to the candidate driving source.

Overview Field 5 Flow (table entry) Source (table) Source (note)

51. Roughly east-west oriented flow originating in millimetre source between 5-16 A and B. 5-16 A, 5-12, and 5-11 form the eastern lobe of the flow, the counter flow is indicated by 5-16 B (and possibly 5-19). The length is measured over 5-16, 5-12, and 5-11, the total length of the flow may be about 2 pc, assuming that it is symmetric about its driving source. The morphology of 5-16 A and B seem to indicate that the flow here is interacting with the walls of its outflow cavity (possibly traced by some reflection nebulosity). 5-12 and 5-11 may be large bow shocks, and are also detected at optical wavelengths (Reipurth et al. 1998, Mader et al. 1999).

55. HH 34 giant flow (Bally & Devine 1994; Devine et al. 1997; Eislöffel & Mundt 1997). The length is measured over the H₂ features seen here only. HH 38/43 further north-west is also an H₂ bright object, but not on the mosaic presented here. In total, the flow extends over more than 3 pc. The HH 34 inner jet (5-21 B) is detected in the H₂ line here for the first time. The counter jet (5-21 C) is detected for the first time at all. The flow position refers to the driving source.

Overview Field 5 Flow (table entry) Source (table) Source (note)

57. Two bright features with a morphology suggestive of small compact bow shocks in a bipolar configuration around BE Ori. The compactness of the bow shocks suggests the presence of a higly collimated jet beam, which itself is not visible neither as H₂ jet nor as optical HH jet (Mader et al. 1999). The flow position refers to the candidate driving source BE Ori.
Overview Field 5 Flow (table entry) Source (table) Source (note)

58. Group of H₂ features in a roughly symmetric bipolar configuration around fan shaped infrared source (candidate driving source). 5-27 A consists of two features, both suggestive of bow shocks heading away from the driving source. 5-27 B and C appear to be a symmetric pair of bow shocks at a greater distance from the driving source. The flow position refers to the candidate driving source.

59. The H₂ features 5-28 and 6-1 form the infrared counterpart to the north-south oriented bipolar molecular outflow V 380 Ori NE (Levreault 1988a; Morgan et al. 1991; Davis et al. 2000b). They indicate the presence of a well collimated, precessing jet. The flow position refers to the candidate driving source.

60. Very poorly defined flow, very uncertain. The flow position refers to the north-eastern knot of 6-7.
Overview Field 6 Flow (table entry) Source (table) Source (note)

61. Flow consisting of faint features from H₂O maser/VLA source (Pravdo et al. 1985) coincident with 6-13. The morphology of this flow is not well defined, the true shape is unclear, possibly 6-11 or 6-6 are also part of a flow from that source. The flow position refers to the candidate driving source.
Overview Field 6 Flow (table entry) Source (table) Source (note)

62. This flow almost certainly is not real: on the one hand, the H₂ and K' data alone suggest that there may be a well collimated flow from a compact source (partly continuum, partly H₂ line emission) at the given position. However, this source is coincident with the tip of the very bright HH-object HH 1, and the continuum emission seen presumably is emission from other lines in the filter, and the H₂ feature 6-10 B/A/D/E presumably is some part of the HH 1/2 flow. This conclusion however is based on optical data, not on the infrared data. Based on the infrared data alone, one would have to identify this as a likely jet. Thus I list it as a candidate flow here, but as a very uncertain one.
Overview Field 6 Flow (table entry) Source (table) Source (note)

63. Several H₂ and optical HH knots associated with reflection nebulosity suggesting a flow cavity from star N³SK50 and a rather poorly collimated flow through the cavity (e.g., Davis et al. 1994; Corcoran & Ray 1995). There is no counterflow detected. The flow position refers to the candidate driving source N³SK50.
Overview Field 6 Flow (table entry) Source (table) Source (note)

64. HH 1/2 outflow system. 6-10 C indicates a very well collimated jet beam, which flows through an illuminated cavity seen as conical reflection nebula. 6-10 B appears to indicate the interaction of a less collimated flow component with the wall of the cavity. 6-10 A is part of the bow shock HH 1. 6-10 D and E seem to indicate a continuation of the flow beyond HH 1, or may belong to a different flow. In the counter lobe, only the bow shock HH 2 (6-15) is seen. The flow position refers to the presumable driving source HH 1/2 VLA1.

Overview Field 6 Flow (table entry) Source (table) Source (note)

66. All features roughly are located along a line, but may as well belong to individual, unknown flows. There is no source identified, the flow position refers to H₂ feature 7-2 A.
Overview Field 7 Flow (table entry) Source (table) Source (note)

Overview Field 7 Flow (table entry) Source (table) Source (note)

70. Short, probably well collimated HH-/H₂ flow from HBC 491 (Strom et al. 1986). The reflection nebulosity associated with this star suggests the presence of an outflow cavity. The flow position refers to the apparent driving source HBC 491.
Overview Field 7 Flow (table entry) Source (table) Source (note)

71. Faint H₂ knots distributed in a roughly bipolar configuration around a very weak infrared continuum source. The compactness of knots A and B may suggest a well collimated flow. The flow position refers to the presumable driving source (the nebulous infrared source).
Overview Field 8 Flow (table entry) Source (table) Source (note)

72. Jet from Haro 4-255 FIR source. Well collimated jet beam (8-4 I, G) terminates in bow shock like working surface (8-4 A; see also Davis & Eislöffel 1995). The association of 8-2 and 8-7 with this flow is uncertain, the length of the flow given here is measured over 8-4 only. The flow position refers to the presumable driving source.
Overview Field 8 Flow (table entry) Source (table) Source (note)

73. The T Tauri star Haro 4-255 drives a well collimated HH jet (Aspin & Reipurth 2000), which terminates in a bow shock which is also detected as H₂ feature (8-6). However, based on the H₂ data alone, this flow would not have been recognized, and is thus listed as an uncertain detection only. The flow position refers to the driving source Haro 4-255.
Overview Field 8 Flow (table entry) Source (table) Source (note)

74. H₂ knots distributed in a roughly symmetric bipolar configuration around a very weak continuum source. The H₂ features appear to outline a pair of bow shocks from this infrared source. The flow morphology is only very poorly constrained. The flow position refers to the apparent driving source.

75. Group of H₂ features possibly outlining a flow from one of the continuum sources associated with 9-3 A and 9-3 B. Alternatively, 9-3 may be part of the giant flow from L1641-S3 MMS1 (# 76). The flow position refers to the middle between 9-3 A and B.

76. L1641-S3 giant flow (see Stanke et al. 2000). Either a rather poorly collimated or a strongly bending flow from L1641-S3 MMS1.
