gratings; ops request to be submitted Fri afternoon for implementation
for use on Sat afternoon (206:17:04:53 )
• 11479: NUV Quicklook Sensitivity
– Initial analysis indicates sensitivity of all four gratings is nominal
– G185M, G225M, and G230L at or slightly above predicted (TV and
ETC) values
– G285M slightly below ground-values
• 11496: PTNe Lamp 2 check; Grating Efficiency Test
– Lamp 2 nominal
– GET results consistent with most recent ground test and continuing
trends for G225M and G285M (consistent with 11479 above)
Recent Activity
• 11470: NUV Initial Internal Wavecals
– Initial analysis has determined wavelength ranges recorded on detector
for all NUV grating central wavelength settings
• Also used data from 11496 lamp 2 testing
– Most stripe B ranges are consistent with OP-01 values; some stripe
A/C ranges differ from predicted by 2 or more encoder steps
– Analysis on Friday will determine whether any default encoder positions
in mech table should be updated
