7.1	WFC3/IR Error Source Checklist

In comparison to the previous IR detectors flown on the Hubble Space Telescope the WFC3/IR detector data is subject to many fewer problems; thereby simplifying the tasks of data reduction and analysis. We present and discuss the known error sources to allow careful data processing, which will result in improved results. Each is identified, its impact on the data is illustrated, and, if available, possible processing solutions are presented.
