RDD as a Function of Temperature

These plots show the temperature dependence of the root-mean-square value of the residual dark distribution (RDD). The values are given in ADU, where one ADU is approximately 3.5 eV. CCD clocking modes and chip temperatures are represented in the following way:

Clocking modes:

CCD mode Color 1 CCD Red 2 CCD Green 4 CCD Blue

Chip temperatures:

Temperature Range Line Type -62 to -61 C Solid -61 to -60 C Dotted -58 to -60 C Dashed

For clarity we only show data from a single chip for each detector. The other chips behave similarly, although the r.m.s. RDD at the nominal temperature is different for each chip.
