PROCEDURE: 3w

TITLE: Internal calibration lamp flats (WFC)

CATEGORY: Verification

PURPOSE: (1) Test whether tungsten calibration lamp works and provides
uniform illumination.  (2) Test spectral model for Tungsten lamps. Only
need to do this for a few broad band filters

FREQUENCY: Run once for each lamp at nominal environmental T.

DETECTOR: WFC

PREREQUISITES: none

HARDWARE REQUIREMENTS: none

SOFTWARE REQUIREMENTS: none

COMMAND MODE: SMS

PROCEDURE/EXPOSURES:  
	GAIN = 2
        Turn tungsten lamp on (see variants below)
        1.  bias                0s
        2.  SDSS g            2.0s
        3.  SDSS r            0.5s
        4.  SDSS i            0.7s
        5.  SDSS z            0.7s
        6.  bias                0s

VARIANTS:	a- Tungsten #1
		b- Tungsten #2

TOTAL EXPOSURES: 6

TOTAL TIME: setup + 6*overhead + 3.9s = 1.17 hr
	(setup = 10min, overhead = 10min)

ANALYSIS:  standard statistical analysis.  Compare count rate to model.
