EFFECT OF OPEN/OPEN UV-FLOOD ON DARK SIGNAL
This plot displays the dark signal in DN/pixel for the HR
dark images taken before and after the open/open uv-flood
of '22-APR-97 08:17:21', '22-APR-97 09:45:19'. The
short (DPE=2) and long (DPE=30) exposures are illustrated.
The time of the flood is indicated by the "dot" in each
panel. The adjacent darkframe was taken about 2
hours after the completion of the flood interval.
From these images alone it is difficult to assert that
the open/open flood had any effect on the total dark
signal -- although the DPE=2 images may sxhibit a
short term effect in the read noise and spurious charge
part of the dark signal.
