STIS 9608

CCD Bias Monitor - Part 2

Monitor the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at
gain=1, and 1x1 at gain = 4, to build up high-S/N superbiases and
track the evolution of hot columns.

STIS CCD Hot Pixel Annealing Cycle 11

The effectiveness of the CCD hot pixel annealing process is assessed
by measuring the dark current behavior before and after annealing and
by searching for any window contamination effects. In addition CTE
performance is examined by looking for traps in a low signal level
flat. Follows on from proposal 8906. 

ACS 9649

ACS internal CTE monitor

The charge transfer efficiency {CTE} of the ACS CCD detectors will
decline as damage due to on-orbit radiation exposure accumulates.
This degradation will be closely monitored at regular intervals,
because it is likely to determine the useful lifetime of the CCDs.
All the data for this program is acquired using internal targets
{lamps} only, so all of the exposures should be taken during Earth
occultation time {but not during SAA passages}. This program emulates
the ACS pre-flight ground calibration and post-launch SMOV testing
{program 8948}, so that results from each epoch can be directly
compared. Extended Pixel Edge Response {EPER} and First Pixel
Response {FPR} data will be obtained over a range of signal levels
for both the Wide Field Channel {WFC}, and the High Resolution
Channel {HRC}. 

ACS 9655

ACS Post-SMOV UV Contamination Monitor

A standard star field {NGC6681} is observed about once a month
through all the ACS broad band UV filters. NGC6681 hosts several UV
spectro - photometric standard stars for which accurate spectra have
been {and will continue to be} measured with STIS. The target cannot
be observed for three months from mid November through to mid
February, so the standard star GRW+70 will be observed twice in its
stead. This programme continues the UV sensitivity monitoring
campaign {ACS SMOV proposal 9010} of the HRC and SBC after the end of
the SMOV period. An SBC dark current measurement is taken as the last
exposure of each SBC sequence. 

ACS 9674

CCD Daily Monitor

This program consists of basic tests to monitor, the read noise, the
development of hot pixels and test for any source of noise in ACS CCD
detectors. This programme will be executed once a day for the entire
lifetime of ACS. 

NICMOS 9702

NICMOS Parallel Thermal Background

NICMOS Camera 2 pure parallel exposures in the F222M and F237M
filters to establish the stability of the HST+NCS+Instrument thermal
emission. This data will be compared against the already available
Camera 3 measurements in F222M which show an increased thermal
background. 

STIS 9708

STIS Pure Parallel Imaging Program: Cycle 11

This is the default archival pure parallel program for STIS during
cycle 11.

WFPC2 9709

POMS Test Proposal: WFII parallel archive proposal

This is the generic target version of the WFPC2 Archival Pure
Parallel program. The program will be used to take parallel images of
random areas of the sky, following the recommendations of the 2002
Parallels Working Group. 

STIS/CCD/MA1 9982

Intergalactic-Ionized Helium toward HS 1700+6416 at maximum QSO
brightness

We propose to measure the UV energy distribution of HS 1700+6416
{z=2.73} in the range 1200-3000 A. Scientific background is that HS
1700 has been observed recently by FUSE in a long integration {390
ksec}. Due to an unexpected brightening of the QSO by a factor of 3
to 4 compared to earlier FUSE and HUT observations the new
observations yielded a HeII forest spectrum of spectacular quality.
The aim of the proposed HST observation is to measure the UV energy
distribution of HS 1700 the knowledge of which is essential for an
optimal evaluation of the FUSE HeII spectrum.
