Summary of relative gain matrices (rgm) computed using sharcsolve and scanning/no-chop observing mode [2006-Jan-25, J. Vaillancourt] All 384 channels: ----------------- - 13 scanned RGM files taken and reduced using sharcsolve - Calculated median gain for each pixel, plotted histogram of relative difference between each pixel and its median for each file - 1 file had histogram with peak significantly different from zero - 1 file had dispersion much larger than other files - 1 file had dispersion moderately larger than other files - remaining 10 files had peaks ~ zero, stddev ~ 1 - 6% - Possible trend in stddev with atm. attenuation/loading (stddev decreased with increasing loading) - No trend in mean deviation from median with atm. loading V-array only: ------------- Same analysis as above, but keep all 13 RGM files - all histograms have peaks ~ zero, stddev ~ 0.4 - 3 % - if remove 3 files mentioned above, stddev ~ 0.4 - 2 % - No trend in stddev with atm. loading - Possible trend in mean deviation with loading (mean increases with loading) H-array only: ------------- Same analysis as above, but keep all 13 RGM files - all histograms have peaks ~ zero, stddev ~ 1 - 8 % - if remove 3 files mentioned above, stddev ~ 1 - 8 % - Possible trend in stddev with atm. attenuation/loading (stddev decreased with increasing loading) - No trend in mean deviation from median with atm. loading Comparison of H/V only with all 384 channels yields the same rgm to within 1%.
