LIST OF PIPELINE PRODUCTS CODES

The names of all pipeline products follow a certain naming convention. This is done to have human-readable rather than technical file names. The naming scheme has been chosen to have the type of product, its date of creation, and its pipeline-relevant parameter values all recognizable from the product name.

Since the begin of period 75 (April 2005), both science and calibration product files are renamed. (Actually, there was a transition phase extending for some instruments from April towards the end of the year 2005).

Before that date only calibration products followed the common scheme which is described here. (Some instruments had their own naming scheme which is described below, if applicable).

The general format of user-oriented product file names is the same for all VLT/VLTI instruments.

Instrument code

All pipeline product names start with two letters which are specific for the instrument. For instance: UVES product names start with 'UV', VISIR names with 'VR'.

Type of product

Next, the product type is coded. The full value is coded in the fits header key HIERARCH.ESO.PRO.CATG. A short form of this tag is coded in four characters being unique per instrument:
1st letter M or P calibration product
  S science product
  G general calibration product (as of P82)
2nd to 4th letter ... type of product

top SINFONI INSTRUMENT CODES

All SINFONI pipeline product names begin with "SI_".

SI_S . . . are science products.

SI_P . . . are calibration products.

 

top SINFONI SCIENCE PIPELINE PRODUCTS

SINFONI pipeline products have the following naming scheme:

SI_<SXXX>_<OBS_ID>_<date_time>_<DET_DIT>_<grating>_<camera_scale>.<ext>

where:

  • <SXXX> is the four letter code uniquely describing the type of product (the first letter is always S for SCIENCE). All these codes are listed below.
  • <OBS_ID> is the Observing Block (OB) number of the observation read from the OBS.ID fits header
  • <date_time> is the UT date and time of the first raw frame measured for the OB (e.g. 2009-01-01T04:31:12); this information is required since OBs can be executed several times
  • <DET_DIT> is a string containing the detector integration time (in seconds) as read from the DET.DIT fits header
  • <grating> is a string containing the instrumental grating used in the observation as read from the INS.GRAT1.NAME fits header (either H, J, K, or H+K)
  • <camera_scale> is a string containing the camera pixel scale used in the observation as read from the INS.OPTI1.NAME fits header (either 25, 100, or 250 mas)
  • a small subset of science products (SI_SBNS or SI_SXBJ) are given an additional 4 digit number (i.e. 0004, 0041, 0042, etc.) . This is needed because these frames are SINGLE exposure cubes (and not the coaddition of all the exposures contained in the OB), and hence all have identical dits, gratings, and camera scales.
  • <ext> is fits

e.g.

SI_SCDJ_186898_2009-01-29T06:48:12_600_H+K_250.fits

SI_SBNS_186898_2009-01-29T06:48:12_600_H+K_250_0041.fits

top CALIBRATION PIPELINE PRODUCTS

SINFONI calibration products come in two flavours: dynamic ones (being updated regularly, short validity), and static ones (never, or rarely updated). Both product types are delivered in the data packages and stored in the archive. The static ones (also called general calibration products) are also delivered in the public pipeline releases.

top Static calibrations. With P81 (April 2008) and thereafter, the static calibration products are also named according to a "nearly" standard SINFONI naming scheme. Before that date, their names did not follow a strict naming scheme. The following table lists the codes in the new name scheme:

 

CODE TYPE OF FILE PRO_CATG EXAMPLE
GARC

arc line reference table (J, H, H+K, K bands)

REF_LINE_ARC

SI_GARC_050331A_H+K.fits

GBPM reference bad pixel map (image) REF_BP_MAP SI_GBPM_050331A_REF_BP_MAP.fits
GCOL position of first slitlet column (table) FIRST_COL SI_GCOL_050331A_FIRST_COL.fits
GDRS first guess wavelength dispersion solution table DRS_SETUP_WAVE SI_GDRS_050331A_DRS_SETUP_WAVE.fits
GATM atmospheric dispersion correction table ATM_REF_CORR SI_GATM_REF_CORR_J_025.fits *

*Note: The atmospheric dispersion correction tables exist for all grisms (S1_J, S2_H, S3_K, and S4_H+K) and for the 25 and 100 mas pixel scales.
The 250 mas pixel is not corrected, since at this pixel scale the maximal shift due to atmospheric dispersion is less than one pixel. The correction of
data cubes for atmospheric dispersion is implemented in SINFONI pipeline versions after 2.0.9.

top Date of origin, version

The date of origin is identical to the date of the raw data measurement. It is coded as, e.g., 050331 for March 31, 2005.

The version of a file is indicated by capital letters always starting with A. Versioning is supported for certain types of files, see the above table. In all other cases, only one version per day is created (always A).

top Instrumental parameters

The instrument parameters characterizing a setup are included in the product name. Most products have the following scheme:

<GRATING><CAMERA_SCALE>

where:

  • GRATING is either J, H, K, or H+K bands (from the INS.GRAT1.NAME fits header)
  • CAMERA_SCALE is the pixel scale as defined by the pre-optics: 250, 100, or 25 mas (from the INS.OPTI1.NAME fits header)

for example:

SI_PKCS_090127D_J_250.fits

DARK products have only a <DET_DIT> exposure time (in seconds) designator (eg. SI_PMDK_090127A_300.fits)

 

Suffix

All product files have extension .fits. They have either image format or binary table format.
