WFC3 IR detector: On-Orbit Performance
Abstract
In the 20 months since Wide Field Camera 3 (WFC3) was installed in the Hubble Space Telescope (HST), the WFC3 team has collected and analyzed a large amount of calibration data. We describe the current status of several IR channel characterization and calibration efforts, including persistence and count-based and count rate-based non-linearity (a.k.a reciprocity failure, or the Bohlin effect). We also summarize the photometric performance of the IR channel, focusing on zeropoints and stability.
