SMOV Status & Planning Meeting Notes
9/10/09
-
Summary – Data analysis of WFC3, COS, and STIS SMOV calibrations continue.
WFC3 image stability occasionally exceeds spec. COS FUV resolution analysis appears to
indicate LSF resolution is below expectations by ~ 20%. NICMOS SMOV commences next
week, though discussions on expanding the filter wheel test are underway. Also, COS NUV
and FUV science is being enabled in next week’s SMS; some GTO and GO visits are
scheduled. The ERO media release occurred Sep. 9. and appears to have been well
received and well reported. As of Sep. 11, all WFC3 SMOV activities are complete. STIS
SMOV is also officially complete. Congratulations to both teams, and all support
personnel, on a well planned and well executed SMOV.

 NICMOS SMOV to commence in SMS 257 on Sep. 15
o DC Transfer Function Test
o Dark Monitoring
o Filter Wheel Test (FWT)
 There is a move afoot to expand the FWT into a
more conservative verification of FW motion
The ERO media release occurred yesterday, Sep. 9.
 Appears to have been well received and reported

A few more Q/S split COS observations (one being la9h02nb) have been
received and successfully dealt with using the new MRGCOS process and
the updated DPAS procedure to deal with them.
Over the holiday weekend, a COS ASN, LA9H02020, became stuck in
calibration. Brian York is looking into it.
An update to the NICMOS CG5 database table, documented in PR 63451, is
to be installed later today.
No fast-tracking for the remainder of this week, but there will be some next
week for NICMOS SMOV activities.
