PERIOD COVERED: 0000Z (UTC) 07/31/00 – 0000Z (UTC) 08/01/00
Daily Status Report as of 214/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed STIS/CCD 8412 (STIS CCD Imaging Flats C8)
The Space Telescope Imaging Spectrograph (CCD) was used to investigate the flat-field stability of the unit over a monthly period. A bias calibration observation was also taken. The observations were executed as scheduled, and no anomalies were noted.
1.2 Complete WF/PC-2 8331 (Probing the Dark Side of Galaxy Formation: HST Imaging of the ISO Ultradeep Survey)
The WF/PC-2 was used to observe the Hubble Deep Field (HDF) which gave astronomers an unprecedented view of the optical and rest–frame–UV side of galaxy formation. However,
new data from ISO and COBE confirms the suspicion that the optical/UV does not tell the whole story. ISO observations have also demonstrated that this is true even in the HDF. These show the presence of ~25 galaxies brighter than ~200MuJy at 15Mum. The observations were completed with no reported anomalies.
1.3 Completed Two Sets of STIS/CCD 8437 (Dark Monitor-Part 2 C8)
The Space Telescope Imaging Spectrograph (CCD) was used to monitor the darks. The proposal completed nominally.
1.4 Completed Four Sets of STIS/CCD 8808 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation III)
The Space Telescope Imaging Spectrograph (CCD) was used to make non-scripted, parallel observations as part of a POMS test proposal. The observations completed with no anomalous activity.
1.5 Completed STIS/CCD 8439 (Bias Monitor-Part 2 C8)
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, to build up high-S/N superbiases and track the evolution of hot columns. The proposal completed with no reported problems.
1.6 Completed Three Sets of WF/PC-2 8826 (Cycle 9 Supplemental Darks pt 1)
The WF/PC-2 was used to perform a T dark calibration program that obtains three dark frames every day in order to provide data for monitoring and characterizing the evolution of hot pixels. There were no reported anomalies.
1.7 Completed STIS/CCD/MA1/MA2 8297 (The Physical State of the Starburst Outflow in NGC1705)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to perform echelle M mode spectroscopy from 1200 Angstrom to 3000 Angstrom of the nearby starburst galaxy NGC1705 to probe the physical conditions in the starburst- driven galactic superwind. The proposal completed with no reported problems.
1.8 Completed Two Sets of WF/PC-2 8805 (POMS Test Proposal: WFII Parallel Archive Proposal Continuation)
The WF/PC-2 was used to perform a 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 Parallels Working. The proposal completed with no reported problems.
1.9 Completed WF/PC-2 8812 (Cycle 9 Internal Monitor)
The WF/PC-2 was used to obtain routine internal monitors for WFPC2 in order to monitor the health of the cameras. A variety of internal exposures are obtained in order to provide a monitor of the integrity of the CCD camera electronics in both bays {gain 7 and gain 15}, a test for quantum efficiency in the CCDs, and a monitor for possible buildup of contaminants on the CCD windows. There were no reported problems
1.10 Completed WF/PC-2 8811 (Cycle 9 Standard Darks)
The WF/PC-2 was used to obtain dark frames every week in order to provide data for the ongoing calibration of the CCD dark current rate, and to monitor and characterize the evolution of hot pixels. Over an extended period these data will also provide a monitor of radiation damage to the CCDs. The proposal completed with no reported problems.
1.11 Completed WF/PC-2 8193 (Comparing the Hosts of High-Z Radio-Quiet Quasars to Lyman Break Galaxies)
The WF/PC-2 was used to try to determine the underlying causes of the rapid cosmological evolution of the quasar population that is a mystery around which is woven many different strands of contemporary
cosmology. The proposal completed nominally.
1.12 Completed STIS/CCD 8870 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation IV)
The Space Telescope Imaging Spectrograph (CCD) was used to make non-scripted, parallel observations as part of a POMS test proposal. The observations completed with no anomalous activity.
1.13 Completed STIS/CCD 8236 (Black Holes and Gas Disks in a Complete Sample of Radio-Loud Ellipticals – II: Kinematics)
The Space Telescope Imaging Spectrograph (CCD) was used to make observations of the radio-loud elliptical galaxy NGC-7626. From these observations we will measure the black hole masses, determine the nature, kinematics, and structure of the central gas disks and obtain a modeled upper limit to their mass accretion rates. A wavelength calibration image was also taken. The observations were completed as planned, and no problems were reported.
1.14 Completed WF/PC-2 8162 (Identifying The Hidden Phases Of Galaxy Evolution)
The WF/PC-2 was used to perform deep surveys in the sub-mm waveband that are revealing a population of very luminous dusty galaxies at high redshifts, which are {a} as a population, producing stars at a rate as large or larger than the optically selected galaxy population at high redshifts and thus presumably producing a substantial fraction of all stars that have ever been produced; and {b} doing so, individually, in systems with bolometric luminosities (i.e. star-formation rates} that are very much larger than typically seen in the optically-selected population). The observations completed with no anomalous activity.
1.15 Completed STIS/CCD 8413 (STIS Yearly CCD Wavelength Monitor)
The Space Telescope Imaging Spectrograph (CCD) was used to execute the yearly CCD wavelength monitoring program. This is a continuation of program #7650 that was executed during in Cycle-7. The observations were completed as planned, and no problems were reported.
1.16 Completed WF/PC-2 8645 (A Survey of Mid-UV Morphology of Nearby Galaxies: Galaxy Structure and Faint Galaxy)
The WF/PC-2 was used to investigate the relation between star formation and the global physical characteristics of galaxies to interpret the morphologies of distant galaxies in terms of their evolutionary status. The observations completed nominally.
