WHAT YOU SHOULD SEE

Data taken with ARC controller (April 2007), and with the array in upside-down (note triangle feature on array is now at the bottom!).

1 second dark: A standard short array-test dark. Should see "zero counts". .sdf file available here	100 second dark: A standard long array-test dark. Should see 15-20 counts. .sdf file available here

4 second HK flat, 4 pix slit: A standard HK spectroscopy flat. Should see counts in range 1000-8000. .sdf file available here	15 second HK arc, 4 pix slit: A standard HK spectroscopy arc. Should see strong, narrow (4-pixel wide) lines. .sdf file available here

40 second short-K IFU flat: A standard short-K IFU flat. Should see counts in range 1000-8000. .sdf file available here	30 second short-K IFU arc: A standard short-K IFU arc. Should see strong, narrow (2-pixel wide) lines. .sdf file available here

Coronagraphic mask: K-band Coron exposure. Taken during day (night sky should be smoother). .sdf file available here	Coronagraphic mask with IRPOL: K-band Coron + Pol exposure. Taken during day (night sky should be smoother). .sdf file available here

THERMAL IMAGING

SATURATING: High counts (25,000-30,000) top and bottom, with low or maybe even negative counts in the middle.	NOT SATURATING: Counts should be 10,000-25,000

WHAT YOU SHOULD NOT SEE

Disabled array data taken with ARC controller; all other images taken with old EDICT system, although the images should look the same if these problems re-occur.

Thermal gradient: A bad 100 sec dark showing the gradient. More details given here	Ice on the UIST window: A daytime K-band image of inside of dark dome Details on clearing ice given here

Image Rotator at 0 degrees: For imaging should be at -90 degrees! Above can see vignetted corners, because the image rotator actually rotates by 45 degrees for every 90 (uses two folding mirrors).	Array disabled: All zeros - Have forgotten to enable the array

Bad channel : Low-frequency sine wave along every 8th column in two quadrants (from summer 2007 - SDF frame)	... ...

ENGINEERING (UCLIENT DATA)

Data taken with ARC controller (Dec 2006), though while still fixing boards, etc. (so striping in bottom-right quadrant not normal).

Stare frame Full array (UCLIENT default settings with srr1024) SDSU-stare.fits	CDS frame Full array (UCLIENT default settings with cds1024) SDSU-cds.fits	NDR frame Full array (UCLIENT default settings with ndr1024) SDSU-ndr.fits
