Find here detailed information about the MIDI QC1 parameters and select plots. ASCII data from the QC1 database will be available in the future.

GENERAL INFORMATION

Some MIDI 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.

All measured QC1 parameters are stored in a database. Their evolution with time is evaluated by the trending process.

INSTRUMENT PROPERTIES TRENDED

The following parameters are monitored and used for instrument trending. The plots are available on the MIDI HC page.

detector

read noise
detector linearity

alignment

position of the reference pixels

dispersive elements (GRISM or PRISM)

transmission of the dispersive elements

Instrumental Transfer Function
