NACO:
Association Rules |
|||||
|
Data Classification and Association is a general requirement for data processing. In the VLT DataFlow raw NACO frames (FITS files) are classified in Garching to be processed by the data reduction pipeline and to be distributed to the individual PIs. Data can be classified as either science data or calibrations . Other classification schemes use the instrument mode and the NACO raw data are processed at two places in the VLT DataFlow:

NACO_img_obs_AutoJitter NACO_img_obs_AutoJitterOffset NACO_img_obs_GenericOffset NACO_img_obs_FixedSkyOffset NACO_coro_obs_Stare NACO_coro_obs_AutoChopNod |

NACO_img_cal_Strehl | OBS.PROG.ID, OBS.ID | two Strehl ratio frames for NAOS | |
NACO_img_acq_MoveToPixel | OBS.PROG.ID, OB.ID | CONICA acquisition | |
NACO_all_cal_Darks | DET.NCORRS.NAME DET.MODE.NAME DET.DIT |
Three keywords are required for unique identification. Note that darks use a weak association in time. If not taken in the same night, take the closest in time. |

NACO_img_cal_TwFlats NACO_img_cal_SkyFlats |
DET.NCORRS.NAME DET.MODE.NAME INS.OPTI3-6.NAME INS.OPTI7.NAME AOS.INS.DICH.POSNAM |
OPTI3-6 is one of the filters, OPTI7 is the objective/camera, AOS.INS.DICH.POSNAM is the dichroic name and NCORRS is again the read mode. Mode is the Gain tag. Twlight flats will be offered in the following three modes: Broad band < 2.5mu in Double_RdRstRd; NB+IB < 2.5mu in FowlerNsamp and Uncorr for > 2.5mu. If other combinations are used in the science frames only the NCORRS will be matched. Note that the twflat recipe produces in addition a badpixel map a error map and a interception map, for which the same association rules apply. Only the objective the filter and the dichroic must match. The detector setting must be known for the lamp flats |
|
NACO_img_cal_LampFlats | DET.NCORRS.NAME DET.MODE.NAME INS.OPTI3-6.NAME INS.OPTI7.NAME | In addition to either twilight flats or skyflats, internal lamp flats are provided in any case. In case a neutral density filter (INS.OPTI3.NAME=ND_Short or ND_Long) is used in addition to BB filters, this key is not matched. The lampflat is matched with the readout mode of the science but not with the DIT of the science. Lampflats do not require dark calibrations in addition. | |
NACO_img_cal_StandardStar | collect all zeropint measurements in all standard filters (J,H,Ks, and L), but no IB,NB filters. The match is strong in time: only those of the same night are taken. | ||
NACO_all_cal_Darks | DET.NCORRS.NAME DET.MODE.NAME DET.DIT | Parameters must match those of the Standard star | |
NACO_img_cal_TwFlats NACO_img_cal_SkyFlats | INS.OPTI3-6.NAME DET.NCORRS.NAME INS.OPTI7.NAME AOS.INS.DICH.POSNAM DET.MODE.NAME | Parameters must match those of the Standard star | |
NACO_all_cal_Darks | DET.NCORRS.NAME DET.MODE.NAME DET.DIT | Parameters must match those of the twilight flat | |
NACO_img_cal_LampFlats | INS.OPTI3-6.NAME DET.NCORRS.NAME INS.OPTI7.NAME AOS.INS.DICH.POSNAM DET.MODE.NAME | In addition to either twilight flats or skyflats, internal lamp flats are provided in any case. In case a neutral density filter is used in addition to BB filters for the bright Standard Star, this key is not matched. |
Table Notes:
These rules differ only in the handling of the standard star with respect to the imaging mode.

NACO_spec_cal_Arcs |
INS.OPTI1.NAME INS.OPTI4.NAME INS.OPTI6.NAME INS.OPTI7.NAME |
OPTI1 is the slit, OPTI4 is the grism, OPTI6 is the filter, and OPTI7 is the objective/camera. Arcs and flats are matched with a weak constraint, meaning they can be taken from other days than the science observation day. Arcs are not taken for the wavelngths lower than 3.0 micron, meaning no Arcs are provided for settings using L54 in SEQ.SPECMODE. |
