To correct the warm pixels for temperature and the small effect of bias due to background/zodiacal brightness, the reference limit (100 e-/s at -19C) has been adjusted and the pixels with values greater than this new "Adj. Warm Limit" have been counted as the "Corr. Warm Pix".
reftemp = reference temperature of -19C CCD Temp = temperature of this calibration ZodiB = zodiacal light contribution for this calibration in e-/sec reflimit = 100 e-/s + zodi Adj. Warm Limit = reflimit * 10**((temp - reftemp) / 21C) (where 21C is the slope of the exponential in this temperature domain which defines the approximate gain of the ACA CCD)
