WFC3 Notebooks

WFC3 Notebooks is the primary repository for analyzing data from the Wide Field Camera 3 on the Hubble Space Telescope. The Jupyter notebooks include tools for general data analysis, WFC3/IR time variable background (TVB), photometry and point spread function (PSF) modeling. This repository contains the complementary notebooks mentioned in the WFC3 Data Handbook. These notebooks include:

General Tools:

• WFC3 Image Displayer and Analyzer

• Exception Report Checklist - WFC3

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

• Masking Persistence in WFC3/IR Images

• Analyzing WFC3/UVIS G280 Exoplanet Transit Observations

WFC3/IR Time Variable Background (TVB):

• WFC3/IR IMA Visualization Tools with an Example of Time Variable Background

• Manual Recalibration of Images using calwf3: Turning off the WFC3/IR Linear Ramp Fit

• Correcting for Helium Line Emission Background in WFC3/IR Exposures using the “Flatten-Ramp” Technique

• Correcting for Scattered Light in WFC3/IR Exposures: Manually Subtracting Bad Reads

• Correcting for Scattered Light in WFC3/IR Exposures: Using calwf3 to Mask Bad Reads

Photometry:

• WFC3/UVIS Filter Transformations with stsynphot

• Flux Unit Conversions with synphot and stsynphot

• Synthetic Photometry Examples for WFC3

• WFC3/UVIS Time-dependent Photometry

• Calculating WFC3 Zeropoints with stsynphot

• WFC3/UVIS Pixel Area Map Corrections for Subarrays

Point Spread Function (PSF):

• HST WFC3 Point Spread Function Modeling

• Downloading WFC3 and WFPC2 PSF Cutouts from MAST

See the WFC3 Instrument Handbook, WFC3 Data Handbook, wfc3tools, and WFC3 Software Tools for more information on instrumentation, data, calibration, and software.
