Upon the exchange of the array in NOTCam:

  1. Update the FITS header keywords DETNAME and CCDNAME to give the correct identification (Jacob).



    NOTCam detector identification, fitsheader keyword names, date of arrival to the NOT, Rockwell/Teledyne chip ID number.
    NOT name CCDNAME DETNAME Rockwell/Teledyne ID Date order Arrival to NOT Status

    1) Note that ID number for SWIR1 on invoice to IDA (Instrumente Centre for Danish Astronomy) was referred to as 8347R#1 #131.


  2. Find the best voltage settings looking at the reset images. This is somewhat time-consuming, and could take half a day. When the best values are found, they should be set automatically at the startup of the sequencer. This must be edited by Jacob. Meanwhile put the values into a copy of the script notcam.volt_newpcb_max and run this upon every restart of the software.

  3. Find the internal focus of the camera. May have changed by very few (~ 50) units. Use the hartmann masks.

  4. Test the alignment of the array with the spectral line calibration lamp and measure the FWHM of the lines all over the FOV. Make sure you have the correct focus for the slit and filter you are using (use gr#1, 128mu slit, H filter and argon lamp). Compare with old values (Amanda). Alignment is expected to change. This requires re-aligning the slits.

  5. Make a new database for the Quality Control if this is a new array, otherwise make sure the output of the QC analysis goes to the correct database (Peter).

  6. As soon as the first detector QC has been made, enter the readnoise and gain values for each quadrant and the QC date into the NOT2MEF program (Jacob).

  7. As soon as the rotation centre has been measured on the sky, enter the x,y values for both cameras as well as the QCR date into the NOT2MEF program (Jacob).
