The WFC3-IR detector exhibits a non-linear response to incident flux. The data reduction pipeline provides a correction for the non-linearity comma which depends on accurate characterization of the response of the detector. To monitor the non-linearity of the WFC3-IR detector comma we use a dark observation followed by two internal flats using the Tungsten lamp at different sampling rates comma and a trailing dark. Any changes measured in the non-linearity will be updated in the calibration reference file comma crucial to providing a correction for accurate photometry. This program is a continuation of the cycle 28 (program 16404) linearity calibration program.
