7.1 WFC3 IR Error Source Overview

In comparison to data from the earlier generation of IR detector flown on the Hubble Space Telescope (NICMOS), the WFC3/IR data's improved quality and performance simplifies the tasks of data reduction and analysis. We present and discuss the known error sources to allow a careful data processing, which will yield improved results. Each is identified, its impact on the data is illustrated, and, if available, possible processing solutions are presented.
