VISIR pipeline: calib codes

VISIR pipeline:
product naming scheme

List of codes for VISIR pipeline products

Names of calibration and science products follow a certain naming convention. This is done to have more user friendly names rather than archive- or original-file names. The naming scheme follows the 'Service Mode Data Package Specifications' in its version of 2004-05-27.

Instrument code

The first two letters of the naming scheme are 'VR' for VISIR, followed by an underscore'_'.

Type of product

The type of product is coded with four letters: The first letter is 'S' for science or 'M' for master calibration file. The remaining three letters correspond to the following naming scheme:

Date of origin, version

The date of origin is identical to the date of the raw data measurement. It is coded as YYMMDD (e.g. 000915 for Oct 15, 2000) in case of calibration products, and as YYYY-MM-DDTHH:MM:SS (full time stamp) in case of science produtcs. The version of a file is indicated by capital letters always starting with A. There is no versioning for science products as they have unique time stamp.

Instrumental parameters

There are several instrumental parameters coded at the end of the product name:

INS.PFOV : pix0.075, pix0.127, - for small and intermediate field of view
INS.FILT1.NAME : name of imaging filter, e.g. filtPAH1_1
INS.RESOL : resolution
INS.GRAT1.WLEN : grating wavelength, e.g 8.8um

Extension

2D product images contain the .fits extension. 1D data with the .tfits extension are given in fits table format. The pipeline provides in addition VLT compliant plain ASCII parameter files with the .paf extension. Extractions of the eclipse log file are given with a .log extension.
