Spectroscopy

The baffle lamps used by NOTCam were added under TCS control, and the lamp status is written to the data-base. The status is now shown in the NOTCam user interface, while it is also written to the FITS headers of NOTCam data. Later these headers will also be added to the FITS headers of data from the other instruments as the baffle lamps are a permanent feature of the telescope independent of NOTCam.

The notcam.calibexp script to take calibration data was upgraded to use the tcs.store and restore scripts that allows to record and restore the status of the TCS. NOTCam spectroscopic calibration exposures require the mirror cover to be closed and opened, and the scripts allow to get back to the correct autoguider filter and restart the autoguiding after the calibrations.

Data to characterise spectroscopy in the Z and Y-filter spectroscopy, have been analysed and preliminary results have been presented.
