Sets the readout speed to SLOW.
2=to: 2!:}Format: SLOW SPEED
2=to: 2!:}Comments: This is the slowest (and lowest noise) of the CCD readout speeds, and is not normally used for direct imaging. If you wish to run the CCD in this mode you must issue this command after every hard or soft reset of the CCD controller. This command is only available from the VHT vocabulary, if it appears not to work type VHT then try again. This instruction can also be issued over the network from the DMS terminal, to do this type >CCDn, where n denotes the network address of the CCD in question; then type SLOW.
