1 - Single Scan

This is the only mode KPF will use.

1. The iXon888 used at Lick hangs every 10^3 - 10^4 exposures in Single Scan Mode, and needed a power cycle to recover. Andor suggested using RunTilAbort mode, which is working well (9.3e6 exposures w/o trouble since dispatcher last started).

2. The manual implies that External Exposure is only available in RTA mode. See section 4, page 50 of the manual, sw version 2.102.

Enabled

Enabling baseline clamp ensures that the bias level does not change between images.

7 - External Exposure (bulb)

All exposure times controlled via the Galil

4 - Image

This is the only read mode KPF will use.

Horizontal Clock Speed

Subframe

(move to adjustable parameter section?)

We will end up taking a subframe in the horizontal 1024 pixel direction. Vertical direction will be full frame.

Binning

1x1 (none)

(move to adjustable parameter section?)

We will never bin in standard mode (but it wouldn’t hurt to have the option in case some unique user comes along)

0 - Return to ambient on shutdown

Sets cooler behaviour on shutdown
