# cmr 2002 Sept. 8 # edited version of opECalib-52114.par to change som values of the # readnoise and all the bias levels to match the data taken since the # summer 2002 shutdown. this is for imaging camera on-the-mountain # checking. # list of changes: i2 RN1 i4 RN0 z4 RN1 z5 RN0 g6 RN1 all astrometric # RN and all bias levels, gain for i2 because the below-mentioned change # got lost in the shuffle of cheking in 52114, and gain for u2 # linearity data added to opECalib-52114.par cmr Thu Jan 31 20:28:43 EST 2002 # opECalib-52114 was in turn derived from opECalib-51627.par using Steve Kent's # new saturation-finding code on run 1659, and was made to replace # opECalib-51798. cmr thinks this file should be used for all data taken # after MJD51790, at least until further notice. this new version # of opECalib-52114 also has the gain of i2 changed to 5.9 to reflect the # change done to the electronics of i2 in summer 2000 which had gotten lost. # for amps with the 0th element of the DN array < 0, abs(DN<0>) # is the LINEARITY_TYPE and DN<1> is the number of coefficients # for the fit type, specified in the linearity array version $Name: v4_9_2 $ mjd 52114 nsteps 1 typedef enum { LINEAR_ILLEGAL = 666 # illegal type; this amp isn't used LINEAR_NONE = 1, # C/R = 1 LINEAR_QUADRATIC, # C/R = 1 + c1 R LINEAR_LOG, # C/R = 1 + c1 lg(R) LINEAR_THRESHLOG, # C/R = 1 + (R
