In comparison to the previous IR detectors flown on the Hubble Space Telescope
the WFC3-IR detector data is subject to much fewer problems; simplifying the task of data reduction and analysis. We list in this chapter the known error sources to allow careful data processing, which will result in improved results.
We present a checklist of potential WFC3-IR instrumental anomalies and potential
data processing problems about which the user should be aware. Each of these is discussed in further detail in the sections that follow: the nature of the problem and its impact on the data is illustrated and, if available, the possible processing solutions are presented. The relevant sections for each anomaly are given in parentheses below.
