INGRID array history

March 2001-August 2001

May 2000-February 2001

date: 27-Mar-2003 (after the accidental (not complete) warm--up of INGRID); INGRID @ Cass, CCC off -- only LN2 but 2 cans
array temperature: 79.0 K
readout noise (post-pre): 8 adu (~32 electrons)
number of hot pixels (in 10s): 7617 (0.73%). Per quadrants: 0.35%, 0.36%, 1.1% and 1.1% of the pixels are hot in quadrants left-up, right-up,right-down and left-down respectively

Dark 10s (r585921pp.fits)
FITS file (gzipped, 1.0Mb) Hot pixel mask
FITS file (gzipped, 23.6Kb)


Dark 10s (r571365pp.fits) FITS file (gzipped, 1.0Mb)	Hot pixel mask FITS file (gzipped, 25.5Kb)

date: 17-May-2002 (after cooling down on the 21st March 2002); INGRID @ Ghrill but CCC working
array temperature: 71.8 K
readout noise (post-pre): 5.1 adu (~20 electrons)
number of hot pixels (in 9.8s): 3961 (0.38%). Per quadrants: 0.19%, 0.21%, 0.57%, and 0.54% of the pixels are hot in quadrants left-up, right-up, right-down and left-down respectively
