#''Readout rate'': Fast (5 MHz - read noise 13.6 electrons) or Slow (0.05 MHz read noise 3.3 electrons)
#''Shutter'': Open must be selected for multiple exposures <60 seconds (time series will therefore typically be 1x1HighFastOpen). Otherwise Auto for longer exposures.
*'''Filter''': Mookodi has [https://topswiki.saao.ac.za/index.php/Mookodi#Specifications two filter magazines], which the OCS calls Filter and Obfilter (below). There needs to be one filter – and only one filter – in the beam at any time, so you need to select one from one of the two magazines. In this box you can select an SDSS filter. If you want to use a clear filter, it is in the next field, so select OUT here.
*'''Obfilter''': If you have selected an SDSS filter in the Filter option, select OUT here. Otherwise select Clear. Do not select OrdBlk_Fltr - this is for spectroscopy.
*'''Slit''': must be OUT.
