FUV Focus Status
• Modeling is underway to simulate the upcoming
focus run using STIS spectrum and raytraced
PSFs.
• Two new targets (Sk-155, WD2218+706) with
STIS spectra chosen to check resolution in
program 11489 (FUV External Spectroscopic
Performance I)
– Updated visits will be submitted soon.
– Plan is to schedule them after the focus adjustment,
early in SMS 243.
5
NUV Sensitivity (11479)
Preliminary Results
• Data for the first three visits, using
GRW+70D5824 and GD71 have allowed us to
derive (preliminary) independent sensitivity
curves for each grating and stripe.
– Similar to prelaunch predictions
• G230L second order contribution still being
quantified (but was expected)

NUV Sensitivity (11479)
Preliminary Results
7
FUV Lower HVNom
• New HVNom values loaded last week.
• HV will be cycled early in SMS 236
(HVLow→OPERATE→HVLow) so that the
HVMax values are loaded to the DCE.
• DCE Memory Dump will be done at the same
time to look for evidence of HV Transients.
8
Target Acquisitions
• Initial looks show that dispersed light and imaging
target acquisitions for both channels have been
performing well.
• Two exposures of 1147205 (NUV Dispersed Light
Acquisitions) were lost last weekend due to
missing lock.
– Preliminary analysis indicates we will not have to
repeat them.
