HUBBLE SPACE TELESCOPE
DAILY REPORT # 3122
PERIOD COVERED: 0000Z (UTC) 05/21/02 – 0000Z (UTC) 05/22/02
OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
NICMOS 8790
NICMOS Post-SAA calibration – CR Persistence Part 1.
A new procedure proposed to alleviate the CR-persistence problem of NICMOS.
Dark frames will be obtained immediately upon exiting the SAA contour 23, and
everytime a NICMOS exposure is scheduled within 50 minutes of coming out of the
SAA. The darks will be obtained in parallel in all three NICMOS Cameras. The
POST-SAA darks will be non-standard reference files available to users with a
USEAFTER date/time mark.
STIS/CCD 8902
Dark Monitor-Part 2.
The Space Telescope Imaging Spectrograph (CCD) was used to monitor the darks.
STIS/CCD 8904
Bias Monitor-Part 2.
The Space Telescope Imaging Spectrograph (CCD) was used to monitor the bias in
the 1×1, 1×2, 2×1, and 2×2 bin settings at gain=1, and 1×1 at gain = 4 in order
to build up high-S/N superbiases and track the evolution of hot columns.
WFPC2 8938
WFPC2 CYCLE 9 SUPPLEMENTAL DARKS pt3/3.
characterizing the evolution of hot pixels.

NICMOS 8989
NICMOS Thermal Background
Observations in NICMOS Camera 3 in the filters F110W, F175W, F240M, F222M,
F160W
will be obtained at a variety of spacecraft attitudes to characterize the
thermal background light from HST+NCS+Instrument which reaches the NICMOS focal
plane.
STIS/CCD 9066
Closing in on the Hydrogen Reionization Edge of the Universe.
The Space Telescope Imaging Spectrograph (CCD) was used in parallel constrain
the Hydrogen reionization edge in emission that marks the transition from a
neutral to a fully ionized IGM at a predicted redshifts.
STIS/CCD/MA1 9154
Spatial Distribution Of The Gas Inside The Beta Pic Disk.
The Space Telescope Imaging Spectrograph (CCD and MA1) was used to investigate
the gas and dust disk surrounding Beta Pictoris that will give clues to the
understanding of the late stages of planetary formation.
NICMOS 9269
NICMOS Parallel Thermal Background
NICMOS Camera 3 pure parallel exposures in the F222M filter will be
obtained for
the entire duration of SMOV to establish the stability of the
HST+NCS+Instrument
thermal emission.
STIS/CCD 9317
Pure Parallel Imaging Program: Cycle 10.
The Space Telescope Imaging Spectrograph (CCD) was used to perform the default
archival pure parallel program for STIS during cycle 10.
WF/PC-2 9318
POMS Test Proposal: WFII Parallel Archive Proposal Continuation.
The WF/PC-2 was used to perform the generic target version of the WFPC2
Archival
Pure Parallel program. The program was used to take parallel images of random
areas of the sky, following the recommendations of the Parallels Working
Group.
WF/PC-2 9319
POMS Test Proposal: WFII Backup Parallel Archive Proposal II.
The WF/PC-2 was used to execute a POMS test proposal, designed to simulate
future scientific plans.
ACS/WFC/HRC 9566
CCD Hot Pixel Annealing.
The Advanced Camera for Surveys (WFC and HRC) was used to perform hot pixel
annealing that will be performed once per month. The CCD TECs will be
turned off
and heaters will be activated to bring the WFC detector temperature to about
+10C. The HRC temperature will reach about 30C. This state will be held for
approximately 24 hours, after which the heaters are turned off, the TECs turned
on, and the CCDs returned to normal operating condition.
