PERIOD COVERED: 0000Z (UTC) 07/05/00 – 0000Z (UTC) 07/06/00
Daily Status Report as of 188/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed 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.
1.2 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.
1.3 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.
1.4 Completed Three 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 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.
1.6 Completed STIS/CCD 8678 (Galaxy Mass and the Fate of the ISM in Candidate Proto-Spheroidals at z~0.2-0.4)
The Space telescope Imaging Spectrograph (CCD) was used to obtain long-slit spectra for a sample of 5 faint blue compact galaxies {BCGs} at z ~ 0.2 to 0.4. The observations completed nominally.
1.7 Completed 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.
1.8 Completed WF/PC-2 8609 (Host Galaxy Luminosities of the Most Luminous QSOs)
The WF/PC-2 was used to determine the factors that decide whether a galaxy is host to a luminous QSO. Recent evidence indicates that host galaxy spheroid mass is a key factor: we want to test the relationship between host galaxy and QSO luminosity at the highest feasible QSO luminosities by measuring the luminosities and profiles of host galaxies for QSOs with -25.8 > M_V > -27.6. Current data in this area are conflicting. The observations completed with no reported anomalies.
1.9 Completed STIS/CCD 8260 (Searching for the Hydrogen Reionization Edge of the Universe at 5HST)
The Space Telescope Imaging Spectrograph (CCD) was used to observe one of 36 parallel orbits {4–5 fields of 5–8 orbits each} to constrain the H Lyman-edge in emission that marks the transition from a neutral to a fully ionized IGM at a predicted zion~eq5–15. This edge is due to recombination from the H Lyman series and Lyman continuum, and can be used to constrain zion, one of the most important unknown quantities in large scale structure and cosmology. The proposal completed nominally.
1.10 Completed STIS/CCD/MA1/MA2 8265 (Reverberation Mapping of a Narrow-Line Seyfert 1 Galaxy)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to monitor the UV spectral variability of the narrow-line Seyfert 1 {NLS1} galaxy AKN 564 at 46 epochs in order to measure the size of the broad emission-line region via reverberation-mapping techniques. This measurement, and the virial mass estimate that follows from it, will provide a key test of NLS1 models and help determine the physical mechanism that underlies the principal component of AGN spectra, the Boroson–Green primary eigenvector. These observations will be undertaken in parallel with X-ray and ground-based optical observations that will allow us for the first time to explore the multiwavelength variability characteristics of this important subclass of active galactic nuclei. The observations completed with no reported problems.
1.11 Completed Two Sets of STIS/MA1 8426 (Cycle 8 MAMA Dark Measurements)
The Space Telescope Imaging Spectrograph (MA1) was used to make a routine Cycle-8 MAMA dark noise calibration measurement. This proposal will provide the primary means of checking on the health of the MAMA detectors. This is done through frequent monitoring of the background count rate. The observations were completed as planned, and no problems were reported.
1.12 Completed WF/PC-2 8457 (UV Earth Flats)
The WF/PC-2 was used to obtain a series of Ultraviolet Earth flats. The observations were completed with no reported problems.
1.13 Completed WF/PC-2 8328 (HST Astrometry to Gauge the Distance of PSR0833-45 {VELA} and PSR0656+14)
The WF/PC-2 was used to make astrometric observations of the reference star STAR-0835 in order study the distance of PSR0833-45 {VELA} and PSR0656+14. High angular resolution, coupled with sensitivity, makes HST the ideal instrument to measure tiny displacements of faint objects, such as those due to proper motions and annual parallaxes of Isolated Neutron Stars. The observations were executed as scheduled, and no anomalies were noted.
1.14 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.
1.15 Completed STIS/CCD/MA1/MA2 8276 (UV Spectroscopic Investigation of any Bright, Newly Discovered Comet)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to investigate a bright comet that was newly discovered during Cycle 8. These comets include comets of any dynamical class. There were no reported problems in any of the observations.
1.16 Completed WF/PC-2 8598 (Snapshot Survey of Extended OIIl Lambda 5007Angstrom Emission in Seyfert Galaxies)
The WF/PC-2 was used for a snapshot survey of narrow band OIII Lambda 5007Angstrom images for a well defined sample of 88 Seyfert galaxies {29 Seyfert 1s and 59 Seyfert 2s}, 18 of which already have data in the archive, selected from a mostly isotropic property, the 60Mum flux. These data will be used: 1} to determine the origin of the misalignment between the accretion disk axis and the host galaxy plane axis, which can be due to mergers with other galaxies, or by the self induced radiation warping; 2} to compare the size and shape of the Narrow Line Regions (NLR) of Seyfert 1s and Seyfert 2s, and to study the frequency of conically shaped NLR in Seyfert galaxies, which are usually unresolved from ground-based observations; and 3} estimate the importance of shocks to the ionization of the NLR. The observations completed with no reported problems.
