IPCS

Check that desired IPCS pixel size has been set (typically 74 x 17 microns for UCLES). If not, adjust x-gain and y-gain potentiometers on IPCS rack in coudé anteroom; read graphs to get voltages which correspond to desired pixel sizes.

Check that IPCS rack is switched to control room.

Set xlines and ylines switches (in control room) to give required number of pixels. The IPCS is normally used with a hardware format of 2048 256, a software window of 2040 240 and starting values of 14 2.

GO
to start data-taking procedures.

RUN
expose (time given by hardware timer)
CONT
continue after a (hardware) HOLD
ABORT
RETURN
exit data taking mode and return to startup
