backlit iris.
L20030123_00004:45:47light level to low for the attenuated rayleigh channel to0EG
give any good chopper data.
L20030123_00004:46:25removing attenuator for chopper characterization 0EG
leaving daystar in the path
L20030123_00104:50:52it apears as if the chopper is open arround bin zero at the 0EG
setting we have been running at and it's only the telescope
FOV overlap function that is contributing to the below
10km attenuation.
L20030123_00105:06:27this is still to little, removing daystar0EG
L20030123_00105:13:08setting up for low alt data collection1
