HUBBLE SPACE TELESCOPE DAILY REPORT # 3114 PERIOD COVERED: 0000Z (UTC) 05/10/02 - 0000Z (UTC) 05/12/02 OBSERVATIONS SCHEDULED AND ACCOMPLISHED: NICMOS 8790 NICMOS Post-SAA calibration - CR Persistence Part 1.A new proceedure 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 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at gain = 4 in order to build up high-S/N superbiases and track the evolution of hot columns. STIS/CCD 8908 CCD Imaging Flats C10. The Space Telescope Imaging Spectrograph (CCD) was used to investigate flat-field stability over a monthly period. STIS/MA1 8922 FUV-MAMA Cycle 10 Flats.The Space Telescope Imaging Spectrograph (MA1) was used to obtain FUV-MAMA observations of the STIS internal Krypton lamp to construct an FUV flat applicable to all FUV modes. WFPC2 8938 WFPC2 CYCLE 9 SUPPLEMENTAL DARKS pt3/3. This dark calibration program obtains 3 dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. WF/PC-2 8940 Cycle 10 Earth Flats.The WF/PC-2 was used to monitor flatfield stability by obtaining sequences of Earth streak flats to construct high quality flat fields for the WF/PC-2 filter set. These flat fields will allow mapping of the OTA illumination pattern and will be used in conjunction with previous internal and external flats to generate new pipeline superflats. ACS/WFC/HRC 8947 Weekly Test.The Advanced Camera for Surveys (WFC and HRC) was used to perform basic tests to monitor, the read noise, the development of hot pixels and test for any source of noise in ACS CCD detectors. This program will be executed at least once a day for the entire lifetime of ACS. NIC/1/2/3 8977 NICMOS Fine Optical Alignment.The Near Infrared Camera and Multi-Object Camera (NIC1, NIC2 and NIC3) was used to perform a series of iterative adjustments of the NICMOS pupil alignment mechanism to establish the optical alignment in focus for cameras all three cameras and tilt for camera 1. Specifically, this activity will be used to establish focus monitoring techniques to accomplish the establishment {or reconfirmation} of PAM focus and X/Y tilt. NICMOS 8993 The purpose of this program is to obtain images that display the panchromatic capability of HST with refurbishment of NICMOS. We will obtain images of two targets using NICMOS, and if possible, ACS as well. Images will be obtained in J and H and Paschen alpha. If ACS is unavailable images will be taken in K as well. Two targets will be imaged. The ULIRG IRAS19297-0406 will be observed under all circumstance. And one object from the list of the Cone Nebula {NGC 2264} and NGC 1241 will be observed. The latter will depend upon the result of ground-based IR imaging of NGC 2264. ACS/SBC 9008 MAMA Initial Turn-on and Anomalous Recovery Procedure.The Advance Camera for Surveys SBC) was used for the initial turn-on of the ACS MAMA detector and to permit recovery after an anomalous shutdown. Anomalous shutdowns can occur as a result of bright object violations which trigger the Bright Scene Detection or Software Global Monitors. Anomalous shutdowns can also occur as a result of MAMA hardware problems. The Initial MAMA turn-on/recovery from anomalous shutdown consists of three tests: a signal processing electronics check, high voltage ramp-up to an intermediate voltage, and high voltage ramp-up to the full operating voltage. During each of the two high voltage ramp-ups, diagnostics are performed during a dark ACCUM. ACS/SBC 9009 MAMA Fold Analysis.The Advanced Camera for Science (SBC) was used to perform a MAMA fold analysis for initial turn-on or anomalous recovery of the MAMA detector. FGS/1 9034 The Masses and Luminosities of Population II Stars.Fine Guidance Sensor 11R was used to observe the mass-luminosity relation {MLR} of Population II stars of which very little is currently known. With the advent of the Hipparcos Catalogue, improved distances to many spectroscopic binaries known to be Pop II systems are now available. After surveying the literature and making reasonable estimates of the secondary masses, we find 13 systems whose minimum separation should be larger than the resolution limit of FGS #1. 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. WF/PC-2 9072 Dynamical Masses of White Dwarfs from Resolved Sirius-Like Binaries.The WF/PC-2 was used to observe resolved "Sirius-like'' systems containing hot white-dwarf companions of cooler main-sequence stars. It is proposed to image them annually in the UV. STIS/CCD/MA1/MA2 9081 Accretion in the Planet-Forming Disks of the TW Hya Association.The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to obtain high signal-to-noise, low resolution ultraviolet spectra of the only two stars in the ~ 10 Myr old TW Hya association that are still accreting to measure the mass accretion rate through their disks. With these measurements proposers will be able to assess the gas content in these disks which show clear signs that dust is rapidly evolving towards planetesimals and planets, and obtain crucial parameters to address the problems of planet migration and survival at 10 Myr, the time-scale for planet formation according to meteoritic and preliminary astronomical evidence. FGS/1 9089 Parallaxes of Cataclysmic Variables: Understanding Their Peculiar Secondary Stars. Fine Guidance Sensor #1 was used to measure precise parallaxes for three additional CVs {WZ Sge, RU Peg, and YZ Cnc}, whose orbital periods span a much larger range than explored in previous observations, allowing examination of how the accretion luminosity and secondary star change with orbital period. STIS/CCD 9114 SINS: The Supernova Intensive Study-- Cycle 10.The Space Telescope Imaging Spectrograph (CCD) was used to perform closer observations of supernovae that will create the chemical history of the Universe, energize the interstellar gas, stiffen the spine of the extragalactic distance scale and provide the only evidence for an accelerating universe. A violent encounter is underway between the fast-moving debris and the stationary inner ring. Monitoring this interaction will help solve the riddles of stellar evolution posed by the enigmatic three-ring system of SN 1987A. Our UV observations of Ly- Alpha emission reveal the present location and velocity of a remarkable reverse shock that provides a unique laboratory for studying fast shocks and a powerful tool for dissecting the structure of the vanished star. STIS/FUV-MAMA 9159 Test of a New Observational Method for Stellar Seismology. Proposal will measure amplitude versus wavelength for the 20 known ell=1 and 9. known ell=2 modes in PG1159-035 using the STIS FUV- MAMA. ACS 9301 Take deep ACS images and grism exposures of fields with very deep infrared imaging data. The combined optical - infrared data and grisms will be uniquely suited to study galaxies at high redshift: very high redshift galaxies from the grism data, and internally red galaxies from the combined optical - IR imaging. The comparison of the grism redshifts with groundbased spectroscopy will enable an evaluation of the effectiveness of the grism for redshift studies. The 3 fields of interest for this study are: 1} HDF North, 2} HDF South, 3} MS1054-03. NICMOS 9316 The purpose of this program is to obtain images that display the panchromatic capability of HST with the refurbished NICMOS. We will obtain images of two targets using NICMOS. Images will be obtained in J, H, and Paschen alpha. Two targets will be imaged: 1. Eta Carinae, which will also be imaged in WFPC2 to account for its variability; and 2. the edge-on galaxy NGC4013, for which NICMOS K-band images will be also obtained, and, in addition, Hubble Heritage WFPC2 images are available.
