The Photometric Calibration of WFC3: SMOV and Cycle 17 Observing Plan
Abstract
The newly installed Wide Field Camera 3 on the Hubble Space Telescope will be extensively used by GOs during Cycle 17 for imaging astrophysical phenomena in the UV, optical, and IR. During SMOV4 and Cycle 17, the WFC3 Instrument Team will measure the photometric performance of both the UVIS and IR cameras. These observations will target a set of bright spectrophotometric standard stars and two nearby star clusters. We describe the observational strategy to measure the photometric zeropoints of all filters and the transformation equations to relate the fluxes of objects measured in these filters to other popular ground and space based systems. A detailed discussion of the rationale for the choice of targets, and the analysis plan, are also presented.
