We describe the procedure for obtaining a MAMA detector anode fold analysis. The procedure for cycle-7 is revised from the SMOV procedure (TIR 97-09) to use the line lamps with neutral density filters in an undispersed mode. In all other respects it is the same as the SMOV procedure. This revision corrects minor inconsistencies with the phase-2 proposal(More)
The installation of the Aft Shroud Cooling System (ASCS) on the next HST servicing mission will increase the scientific productivity of STIS by reducing the dark current in the MAMA detectors. The " dark glow " now observed in the FUV-MAMA detector is expected to go away at the ~24 ο C nominal operating temperature after SM3. For the NUV-MAMA, typical dark(More)
An on-orbit flat-field monitoring program was initiated for the MAMA detectors with the goals of comparing the pre-launch flat-field characteristics with those observed on-orbit, measuring the stability of the FUV-and NUV-flats, and creating updates to the reference flats. We found that the NUV-MAMA flat-field images at nominal (1024x1024) resolution are(More)
Ground-based adaptive optics (AO) in the infrared has made exceptional advances in approaching space-like image quality at higher collecting area. Optical-wavelength applications are now also growing in scope. We therefore provide here a comparison of the pros and cons of observational capabilities from the ground and from space at optical wavelengths. With(More)
We describe calstis2, the calstis calibration module which combines CRSPLIT and repeated exposures to produce a single, cosmic ray rejected image. Cosmic ray rejection in the STIS pipeline employs a noise model and parameterized rejection criteria to identify and exclude discrepant values in forming the output image. The calstis pipeline is able to perform(More)
The STIS CCD exhibits fringing in the near-IR which limits the signal-to-noise obtainable at wavelengths longward of 7000 A in the G750L and G750M spectral modes. The fringing can be largely rectified by the application of a flat field (a so called 'fringe flat') taken contemporaneously with the science data, without allowing motion of the Mode Select(More)

We describe the methods and procedures developed to obtain a near-automatic combination of WFPC2 images obtained as part of the WFPC2 Archival Pure Parallels program. Several techniques have been developed or refined to ensure proper alignment, registration, and combination of overlapping images that can be obtained at different times and with different(More)

CONTENTS Foreword It gives me great pleasure to see the publication of Getting Inside Men's Health. This report provides us with valuable and wide-ranging insights into many of the key issues pertaining to men's health. The report is very timely, in that it will have an important function in terms of informing the development of a National Policy on Men's(More)
