Data product names
Pipeline product codes
The names of all calibration 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 setup values recognizable in the product name.
The general format of user-oriented product file names is the same for all
On the archive interface, the master calibrations can be associated to science files and downloaded. Then they carry
technical filenames (the archive filename ARCFILE). In order to rename them to the
original filenames, search for the fits header key ORIGFILE. The naming scheme
of ORIGFILE is described here.
All product names start with two letters which are specific for the
instrument. For instance: UVES product names start with 'UV', VISIR names with
The full value of the product category is coded in the FITS header
key HIERARCH.ESO.PRO.CATG. A short form of this tag is encoded in four
characters being unique per instrument:
| 1st letter || M or P || calibration product|
| || G || general (static) calibration product|
| 2nd to 4th letter || ... || type of product|
Calibration products come in two flavours: dynamic ones (being updated
regularly, short validity), and static ones (never or rarely updated). The
static ones are also called 'general' because they often are not derived from
raw data (like e.g. a line catalogue).
product types are stored in the archive and are available for download through
the calSelector service.
All SINFONI pipeline product names begin with "SI_".
SI_S . . . are science products.
SI_P . . . are calibration products.
Codes for calibration 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.

The following table lists the codes for the static calibrations:
| 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.
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).
The instrument parameters characterizing a setup are included in the product name. Most products have the following scheme:
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)
DARK products have only a exposure time (in seconds) designator (eg. SI_PMDK_090127A_300.fits)
All product files have extension .fits. They have either image format or binary table format.
