Closing down (End of the night)

Darks and flats

Darks can be saved from the fircam_ctrl terminal with :

pls.eon.save_darks(block_light_on_the_bench=True)

Flats can be saved from the fircam_ctrl terminal with :

pls.eon.save_flats()

To do both, one after the other (before going to bed):

pls.eon.take_all_calibs()

These codes will look for every parameters of readout mode and exposition time saved during the night and take darks/flats with the corresponding parameters. The exposition time of the flats are set independently.

Alternatively, darks/flats with set parameters can be saved with :

pls.eon.save_single_dark(detmod = {str, readout mode value to use}, exptime = {float, exposition time to use}, block_light_on_the_bench=True)

pls.eon.save_single_flat(detmod = {str, readout mode value to use}, exptime = {float, exposition time to use})

Note : block_light_on_the_bench is False by default, setting it to true will block light on other instruments.

Don’t forget

  • After logging to sc20 :

    • If you have used the superK: superk power off

    • If you have used the FIRST internal calibration unit: nps 2 5 off to shutdown the flat lamp,

    • and first_pickoff out to remove the calibration pickup mirror

    • Ending with firstpl_pickoff out and vis_block in is a good reflex

A quick command to be sure is :

ssh sc20 " superk power off; first_pickoff out; firstpl_pickoff out; vis_block in; nps 2 5 off "
