GENERAL INFORMATION

Some AMBER calibration data are presently monitored to extract information about their quality and the instrument performance. The quality information is extracted into so-called QC parameters.

AMBER calibration data are pipeline-processed to create calibration products. The quality of the products is measured by QC1 parameters. Most QC1 parameters are obtained by pipeline procedures; some are measured by post-pipeline recipes.

The evolution of the QC1 parameters with time is evaluated by the trending process.

From P78, we are measuring some QC1 parameters from the technical calibration: Beam Position (position of the reference pixels for each instrument setting) and from the Pixel to Visibility Map (P2VM): the internal instrumental Transfer Function and the offset between the different channels .

INSTRUMENT PROPERTIES TRENDED

From P78 the following parameters are trended :

Beam Position (data taken with beam A-B-C in the different spectral channels (J-H-K) with the Coldstop (used as a reference) and with/without the beam Combiner (BCD)

shift in X and Y measured between the data taken with the Coldstop and with/without the Beam combiner
position of the beams (A-B-C) for the different instrument settings (J-H-K channels, with and without Beam Combiner)
flux for the different settings
position angel of the beam

In the P2VM

trending of the internal TF in the different spectral channels
trending of the value of the offset between the photometric channels
