Project Description:

Goal:

• Produce a calibration file with the moments of the response of every pixel in the focal plane.
• If necessary, we want to include the calibration file in the Level 2 to 2.1 processing pipeline.

Methods:

• Making image simulations of the Galactic Bulge Time Domain Survey and calibration fields in Section 2.5 of WFI On-Orbit Calibration plan
• Creating a pipeline to simultaneously solve for 1.8 billion pixel moments from a set of images
• Validate that this pipeline works using our simulated images.
• Coordinating with the Calibration Working Group and SOC representatives on optimizing the observations and dithering plan, as well as analysis methods

Running the code:

imageSim.py contains the code to make oversampled/high resolution Roman images. An example configuration file is provided in example_test.yaml.

Post processing functions live in processImage.py. In your local repository, you can import functions

from processImage import compute_pixel_weights

and call it as needed.
