IR Blob Photometry Test
Abstract
The WFC3 IR blobs are absorption regions caused by an unknown contaminant on the Chanel Select Mechanism {CSM}. In ISR WFC 2010-06 the blob absorption is shown to have a mean difference of 4% between F125W and F160W. The goal of this proposal is to more completely measure the wavelength dependence of the blob absorption. This is done by performing photometry on the HST standard star GD-153 when it is placed on a blob in 4 different filters.
