WFC 3 2008 - 32 WFC 3 Optical Alignment Characterization in Thermal - Vacuum Test # 3
نویسنده
چکیده
We have performed an assessment of the optical alignment of the WFC3 instrument in its final flight configuration, including the UVIS-1’ and IR-4 detectors, during the 3 thermal-vac test in March 2008. Both detectors are found to be aligned to well within tolerance in all degrees of freedom. The corrector settings, after adjustment to optimize image quality, are within the budgeted range for ground alignment, leaving ample range for on-orbit alignment optimization. The UVIS and IR fields of view are concentric to within ~1 arcsec and their respective AXIS-2 orientations are aligned to <0.1 deg at field center.

WFC 3 UVIS PSF Evaluation in Thermal - Vacuum Test # 3
We have assessed the image quality of the WFC3 UVIS channel in a flight-like thermalvacuum environment, and with its flight detector installed. Point source measurements at 16 field positions and four wavelengths indicate excellent imaging performance for the UVIS channel. Encircled energies readily meet expectations over the field, with CASTLE stimulus illumination. Models including the mid-fr...
متن کاملWFC3 TV2 Testing: IR Intrapixel sensitivity
We derive an approximate intrapixel sensitivity variation (IPSV) of the IR-1 detector of WFC3 from ground-test imagery. The purpose was to assess whether additional testing of this sort should be performed in Thermal Vacuum 3 (TV3) testing, scheduled to commence in February 2008. Whereas NICMOS exhibits IPSV as large as 40%, peak to valley, in the photometry of stars observed in J band with the...

OBJECTIVES The aims of this study of Japanese married employees were: 1) to examine the relationship between work-related factors and work-to-family conflict (WFC); 2) to examine the relationship between WFC and fatigue and depression; and 3) to explore the role of family togetherness in a path between WFC and health. METHODS A cross-sectional survey was conducted among employees belonging to...

____________________________________________________________________________ Abstract The present ISR describes the encircled energy(EE) analysis of pinhole images made on the M10 WFC3 1R-MUX at the Goddard Space Flight Center (GSFC) Detector Characterization Lab (DCL) on 29 May 2001. Analysis shows that the pinhole image’s centroid is stable within a 1-pixel area and the 80% of the encircled e...
متن کاملCorrelating the WFC and the IBIS hard X-ray surveys
During the operational life of BeppoSax, the Wide Field Camera observations covered almost the full sky at different epochs. The energy coverage, wide field of view and imaging capabilities share many commonalities with IBIS, the gamma-ray telescope onboard INTEGRAL satellite. We mosaicked all the available single pointing WFC observation images and then we searched the map for persistent and t...
