# Grism Spectroscopy
Here are brief descriptions of the WFC3 Notebooks for grism spectroscopy 
analysis.

## 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, spectrum extraction, and light curve
generation.

## Slitlessutils Cookbook: Spectral Extraction for WFC3/IR
This notebook demonstrates an end-to-end workflow for extracting 1D spectra from
G102 or G141 data using `slitlessutils`. This example guides users through the 
recommended procedure for analyzing slitless data, including downloading data, 
preparing direct and dispersed images, performing background subtraction, and 
executing the traditional extraction mode.

## Slitlessutils Cookbook: Spectral Extraction for WFC3/UVIS Full-Frame
This notebook demonstrates an end-to-end workflow for extracting 1D spectra from
G280 full-frame data using `slitlessutils`. This example guides users through the 
recommended procedure for analyzing slitless data, including downloading data, 
preparing direct and dispersed images, performing background subtraction, and 
executing the traditional extraction mode.

## Slitlessutils Cookbook: Spectral Extraction for WFC3/UVIS Subarray
This notebook demonstrates an end-to-end workflow for extracting 1D spectra from
G280 subarray data using `slitlessutils`. This example guides users through the 
recommended procedure for analyzing slitless data, including downloading data, 
preparing direct and dispersed images, performing background subtraction, and 
executing the traditional extraction mode.
