WFC3: Status, Calibrations and Advice for the CY24 Observers
Abstract
The Wide Field Camera 3 is UV, Visible and near Infrared Camera on boar of the Hubble Space Telescope. We report on the current status of the instrument and on the recent significant improvements in the photometric, flat fields, dark current, and CTE calibrations for the UVIS channel. As a result of this effort we obtained the new independent solutions for the two CCD detectors, and have improved the zero points and color terms in the near-UV and visual wavelengths. We report on the improved astrometric solutions and PSF calibrations. We also highlight new observing strategies recently developed to allow efficient observations of very wide fields of view. Finally new tools for the planning and extraction of slittles spectroscopic observations of crowded fields are presented.
