/* Biases and flats */
# Move the fold mirror into the beam: on the right-hand side of the TCS GUI there is a large green button that will either say "FOLD MIRROR IS IN BEAM", or "FOLD MIRROR IS OUT OF BEAM". If it doesn't say the former, click it to make it so.
# Park the guide camera in the top-right-hand corner of the guide star field of view (represented by the finderchart on the TCS): click "GoTo" in the TCS GUI: XY Slides Control, and enter '''X=500, Y=14000'''. Wait a few moments for the camera to move then check that it reached the desired coordinates.
# '''For biases''': on the SHOC GUI, '''insert the U filter''' into the beam. '''This is currently necessary due to a light leak''' caused by an orange LED, not detected in the U band.
# Take biases or flats as per the usual SHOC procedures.
