General Tools

Here are brief descriptions of WFC3 Notebooks for general tools:

WFC3 Image Displayer and Analyzer

We present display_image, a tool for displaying full images with metadata, individual WFC3/UVIS chip images, a section of an image with various colormaps/scaling, and individual WFC3/IR ima reads. In addition, we present row_column_stats, a tool for computing row and column statistics for the types of WFC3 images previously mentioned.

Exception Report Checklist - WFC3

We present the steps that should be taken when an observer receives a WFC3 Exception Report Email.

Processing WFC3/UVIS Data with calwf3 Using the v1.0 CTE-Correction

We compare calwf3 v1.0 CTE correction versus v2.0, and explore when each version is useful. v1.0 will provide the most up-to-date calibration procedures such as time-dependent photometric corrections and zeropoints, while also including the v1.0 CTE correction.

Equalizing Amplifier Offsets in FLC/FLT Images

The WFC3/UVIS detector has four amplifiers (A, B, C, D), each covering one quadrant of the 4Kx4K pixel field. Even after the standard calwf3 pipeline reduction, small offsets to the bias level can persist between quadrants. These offsets are relatively constant across each quadrant, and sometimes show up as visible to the eye, with some amps brighter than others. In this notebook, you will be guided through how to determine the amplifier-dependent bias offsets in a Wide Field Camera 3 (WFC3) UVIS channel image and equalize the bias levels in each amplifier (amp) to the average across the image.
