Data challenge for 3x2pt

The main goals of this first data challenge are:

• Train everyone on using Cocoa with their local resources
• Study “User variance” in obtaining results and interpreting outcome (e.g. differences in samplers/plotting routines/smoothing)
• Study differences in more complex data vector scenarios (systematics)
• Publish paper documenting the challenge and exploring the impact of systematics on Roman baseline constraints

Instructions:

• Download the latest version of cocoa
• Use the Roman_real and Roman_fourier project repositories for your analysis
• Use the data vectors, covariances, redshift information that are in the "data_challenge1_fourier_medium" and "data_challenge1_real_medium" respectively
• Enter your results into a table similar to the file "YOURTEAMNAME_results.tex"
• Submit your results via email to timeifler_at_arizona.edu

Each Directory Contains:

• Covariance matrix
• Redshift distribution
• Data vector
• Additional information on specific scenario

General details:

• Data challenge 1 uses a LCDM cosmology
• Lens = source. We use the same redshift distriutions and photo-z uncertainties for both samples.
