... of Cycle 7 calibrations, we will provide a more proper measure of the CTE by performing CCD imagery of a field in OmegaCentauri (a globular cluster) at 2 telescope roll angles different by 180 degrees, so that the CTE will follow from the comparison of ...

... As part of the standard calibration of WFC3 we have used observation of the rich globular cluster OmegaCentauri to compare the flux of the same stars on different position of the detector and derive a correction to remove the remaining low-frequency ...
... Corrections as large as 0.1 mag have been found for blob-impacted stars in OmegaCentauri, and the accuracy of the corrected photometry is comparable to the photometric accuracy for stars in blob-free regions ( WFC3 ISR 2015-06 ). ...
