- W2065739969 abstract "A new IR detector (IR1; FPA129) was housed in WFC3 during the most recent campaign of thermal vaccum (TV) ground testing at GSFC. We performed measurements of the IR channel throughput over the course of ground testing, and found that the throughput is near expectations on the blue end of the IR channel wavelength range, but approximately 20% lower than expectations on the red end. This is in contrast to the results of the first WFC3 TV tests in 2004, when the previous IR detector (IR2; FPA064) was in the instrument; there, we found a grey deficiency of 15% in the measured throughput. The throughput measurements in the current campaign were repeated many times, with many variations on the test procedure, to understand the strong variations in the calculated throughput. In the end, these variations were traced to an instability in the optical stimulus used for these tests, not the WFC3 optics or detector. Unfortunately, this problem means that all of the IR1 images in the archive record an erroneous value for the optical stimulus flux. Most of these records cannot be corrected, due to the unknown state of the optical stimulus at the time the data were obtained, but the final two throughput tests were performed in tandem with a calibration of the optical stimulus that accounted for these systematic errors; the correction from this contemporaneous calibration has been applied here." @default.
