Current Performance

Using a 1024x1024 Hawaii-I array and an 8-inch telescope
End to end throughput (J & H) ~6-8%
Intrinsic detector dark current is 0.03 e/sec/pix
Instrument backgrounds (e/s/pix): 0.15 (J), 0.17 (H-short), ~2 (H-long)
Readnoise 17 e rms per read
Sky-sky noise 0 lim flux of 2e-18 ergs cm-2 sec-1 in 3 hours on an 8-m telescope
Line FWHM 1.4 pixels = 3.1 Angstroms (400 l/mm)
