Spectroscopy

Due to the continuing problems of the slow starting of the Argon baffle lamp, a new AC type power supply was purchased and installed. This new PSU seems to have solved the timing issue. As delays are no longer an issue, the script to take calibration exposures can be made more efficient.

Specific instructions have been provided on the web on how to replace a spectral calibration baffle lamp.

The acquisition script to center a star includes measuring the slit position as it varies due to flexure of the instrument. A problem occurred in which the slit position was not properly determined, and observations were done without the object in the slit. As the slits in NOTCam are permanently mounted, the precise position of the slit is still fairly well defined, and a sanity check will be added to the target acquisition script that warns if the measured slit position is far away from the nominal position.
