11552: Characterization of the
WFC3 IR Grisms
• Objective: Verify image displacement, spectral trace and
dispersion, and throughput of the IR G102 and G141
grisms as a function of position on the FOV.
• Activity: Observe GD 153 in 5 point pattern. Obtain
exposures at 9 locations within the FOV of PN HB12.
• 4 visits, 4 orbits.
• Results:
– Compared to predicted values from ground tests
– throughput is ~10% higher
– wavelength solution is good, ~ 1%

11549: UVIS and IR Pointing
• Objective: Measure the pointing stability of the WFC3
UVIS and IR channels with a series of short observations
of a globular cluster.
• Activity: 36 orbits
– Observations are taken:
• 1) constant thermal attitude for 10 orbits then 2 orbits
• 2) hot thermal attitude for 10 orbits then 2 orbits in cold attitude.
• 3) cold thermal attitude for 10 orbits, then 2 orbits in hot attitude
• Results:
– Match predicted values based on ground tests
• measured positions are stable to +/- 0.1 pixels in x and y
• average offset is below 0.2 pixels
• maximum offset is 0.25 pixels

Other Updates
Ongoing investigations:
• “Blobs” observed in external images– ‘stuff’ on the CSM, confirmed through shift in CSM position,
blobs moved with change CSM position
– telemetric study of position shift ongoing
• Light Leaks
– cross contamination program
•
The effect formerly known as IR QEH (TEFKAQ)
– DCL at GSFC are performing tests on similar IR detectors, can
reproduce the effect
