چکیده
____________________________________________________________________________ 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 energy is contained within a radius of 1.08 pixels of the pinhole center, vs. 86% of the energy within 0.83 pixels in the theoretical limit. We analyze the systematic error introduced by the strong undersampling of the PSF showing that the standard centroid analysis overestimates the encircled energy for any given radius.

Stability and Accuracy of HRC and WFC Shutters
Calibration observations (9662) have been used to quantify precise exposure time values, stability and shading effects down to the shortest allowed exposures (0.1s HRC, 0.5s WFC). A few of the shortest exposure times differ by up to 4% from nominal values, and we recommend for these cases that CALACS, or its reference files be changed to use the measured exposure times. In general no significan...
متن کاملACS Distortion derived from RAS-HOMS Measurements
In the February 2001 calibration campaign at Ball Aerospace, measurements were made using RAS-HOMS. Two sets of measurements were performed to derive the ACS distortion patterns. A Ronchi ruling was placed at the image plane to provide a reference square grid. Also a series of laser point images were placed at measured positions to simulate stellar images. The ruling measurements define the sha...

Following the recovery of ACS with the side-2 electronics in July 2006, the temperature of the WFC detector was lowered from-77C to-81C in an effort to mitigate the impact of CTE and hot pixels. As predicted, the temperature change caused a slight loss in detector sensitivity. By using relative photometry of 47 Tuc before and after the temperature change, corrections to the WFC photometric zero...
متن کاملWFC 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 کاملOverview of the Advanced Camera for Surveys On-orbit Performance
We present an overview of the ACS on-orbit performance based on the calibration observations taken during the first three months of ACS operations. The ACS meets or exceeds all of its important performance specifications. The WFC and HRC FWHM and 50% encircled energy diameters at 555 nm are 0.088′′ and 0.14′′, and 0.050′′ and 0.10′′. The average rms WFC and HRC read noises are 5.0 e and 4.7 e. ...
