ABSTRACT
This program will obtain a direct calibration of photometric losses due to imperfect
CTE by imaging stars in 47 Tuc.
OBSERVING DESCRIPTION
Proposal 11880 (STScI Edit Number: 0, Created: Monday, March 23, 2009 8:48:38 PM EST) - Overview
Observations of 47 Tuc with half-FOV sized dithers, various filters, and exposure times are used to achieve different background levels to
characterize impact of CTE on photometry. For each pointing we will obtain 2 CR-SPLITs to allow cosmic ray rejection and provide a set of “clean”
stars for the analysis of CTE effects on photometry. More specifically, since the CTE also depends on the background level, we will obtain 4
different background levels for HRC and 6 for WFC, using the F502N and F606W filters and different exposure times, from 30s to 400s per
exposure. In this way, we will obtain background levels ranging from ~0 to ~50 e-/pixel. Thus the total number of exposures for WFC is 6 (bkg
levels) x2 (CR-SPLIT) x 3 (positions on the sky) = 36. Since it is crucial to obtain an almost constant sky level, we will request “low sky”. Four to
five images can be done each orbit so the total orbit calculation for WFC leads to 8 orbits. For HRC, we will keep the field fixed and perform readout
using 3 different amplifiers. Therefore 4 (bkg levels) x 2 (CR-SPLIT) x 3 (amplifiers) = 24 HRC images can be obtained in 3 orbits. Therefore, the
total number of requested orbits for this Cycle is 11.
