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.

Masking Persistence in WFC3/IR Images

We present how to use the WFC3/IR persistence model to flag pixels affected by persistence in the calibrated (FLT) science images. When the images are sufficiently dithered to step over the observed persistence artifacts, AstroDrizzle may be used to exclude those flagged pixels when combining the FLT frames.

Analyzing WFC3/UVIS G280 Exoplanet Transit Observations

We present the reduction and analysis of exoplanet transit observations of the hot Jupiter HAT-P-41b taken with the WFC3/UVIS G280 grism. The notebook demonstrates source finding, background subtraction, cosmic ray rejection, subarray embedding, spectral trace fitting, spectum extraction, and light curve generation.
