Performance:

Filter	J	H	Ks	units	Notes
Wavelength	1.25	1.65	2.16	microns	1
Bandwidth	0.25	0.30	0.33	microns	2
Zero Point	24.9	24.7	24.3	mag	3
Background	50	300	700	ADU/sec/pix	4

Notes:

(1) Central wavelength in microns.

(2) Bandpass FWHM in microns.

(3) Zero point magnitude corresponds to 2.5*log₁₀(ADU/sec) from a 0^th magnitude star.

(4) Sky backgrounds in ADU/sec/pixel for a background of 16.1, 14, and 12.6 mag per arcsec² in J, H, and Ks, respectively. These backgrounds were measured in April 2004.
