Considerations for using Spatial Scans with WFC3
نویسنده
چکیده
We discuss considerations for preparing observations using spatial scans with WFC3 for two categories of intended reader: 1) the general observer preparing an observation, and 2) a contact scientist reviewing a phase 2 proposal. Coincidentally and conveniently, the IR spectroscopic Exposure Time Calculator’s “brightest pixel” value in electrons accurately predicts (within 5%) the peak value of a spatially-scanned IR spectrum in digital numbers per pixel (DN/pixel).

Photometric Repeatability of Scanned Imagery: UVIS
We provide the preliminary results of a study on the photometric repeatability of spatial scans of bright, isolated white dwarf stars with the UVIS channel of the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST). We analyze straight-line scans from the first pair of identical orbits of HST program 14878 to assess if sub 0.1% repeatability can be attained with WFC3/UVIS. This study...
متن کاملOptimization of an ultra-high-resolution rectangular pixelated parallel-hole collimator with a CZT pixelated semiconductor detector for HiRe-SPECT system
Introduction: In nuclear medicine, the use of a pixelated semiconductor detector such as CZT is an of growing interest for introducing new devices. Especially, the spatial resolution can be improved by using a pixelated parallel-hole collimator with equal holes and pixel sizes based on the pixelated detector. The purpose of this study was to compare the effect of pixelated and ...
متن کاملPerformance of the WFC3 Replacement IR Filters
This report summarizes the performance of the three new replacement filters (F110W, F125W, and F140W) installed in the WFC3 IR filter wheel; the two new IR grisms are discussed in a separate report. The intent is to record for future reference the as-built properties of the new filters, providing an addendum to the original WFC3 document which presented the characteristics of the IR filter set ...
متن کاملWFC3/UVIS Photometric Transformations
We provide photometric transformation coefficients for converting magnitudes from the native WFC3/UVIS filter passbands to Johnson/Cousins UBVRI passbands in ABMAG, STMAG and VEGAMAG system. The transformation coefficients have been calculated both for UVIS1 and UVIS2 chips, for stars of various spectral types and a range blackbody temperatures using synthetic stellar/black-body models. We also...
متن کاملEvaluation of Selection Criteria for WFC3 Replacement IR Grisms
This report describes the rationale for recommending focus as the primary selection criterion in choosing the final IR replacement grisms. Introduction Instrument-level imaging during the first thermal vacuum ground test of the WFC3 IR channel in the fall of 2004 revealed that while the IR filters performed as expected, well within specification, the grisms produced significantly out-of-focus, ...
