Calibration data for CRIRES are taken for two purposes:
assess the instrumental status
calibrate SCIENCE data.
CRIRES calibration data are in general taken during daytime. On request
by the user, also night-time calibrations can be obtained as part of the
Observing Block which generates the SCIENCE data ("attached calibrations").
Telluric and spectro-photometric standard stars are observed upon request.
The following calibration data are taken as part
of the daily CRIRES calibration plan and/or upon request by the user.
Data types are identified by the DPR TYPE keyword in the FITS headers.
After production and certification, the calibration products are renamed
with a more user-friendly scheme which includes type, creation date and
relevant setting parameters.
The processing of CRIRES calibration frames requires a cascaded scheme
where the mutual dependencies of products and raw frames are respected.
The proper sequence of all these production steps is called the calibration
cascade.
Within that cascade, all products are checked with respect to their quality
and their relationship in time. This means e.g. that a dispersion solution
is not only generated using an arbitrary quality-checked solution, but
that specific solution is chosen which is closest in time.
All products created by DFO Garching follow the calibration cascade.
On contrary, Paranal-processed science data never use the up-to-date calibration
products but pre-manufactured standard solutions that are possibly several
months old.
STATIC
CALIBRATION TABLES
The following static calibration tables (the ones not being regularly
processed from raw calibration data) are required for CRIRES data processing:
line tables for ThAr emission lines, N2O absorption lines, and sky
lines
standard star fluxes
configuration of the physical model.
They come as FITS tables and are part of the Service Mode delivery.
The static
tables can be downloaded as gzipped tar file here
[19 MB, created in February 2012].
In addition, there are maps of the coefficients for non-linearity correction which are updated when necessary.
