Repository to hold the SRM tasks as issues
The Science Roadmap contains the Latex document with key projects, objectives and tasks. This repo parses the latex document to extract the tasks as issues (with associated prerequisites, labels, and milestones)
Define the range of values for each null test that would be considered ``null '' . i.e. for a systematics-free catalog with appropriate noise properties, what range of values could be obtained from each null test.
For each of these systematics, verify that the systematic is adequately tested by at least one of the null tests. i.e. Does a catalog with a significant systematic trigger a failure of at least one null test. If not, this means we either need to add another null test or find some other way to set a prior on the level of the systematic. Prereq #23 Prereq #22 Prereq #27 Prereq #26 Prereq #25 Prereq #24 Prereq #312 Prereq #391
Develop an approximate framework to propagate image-level systematics to shear two-point function biases via shear calibration errors using the \WLImSim code. This pipeline should accomodate sensor effects, PSF inference errors, and source extraction errors (including deblending), but in a fast and flexible implementation (trading physical fidelity for speed of development and execution). Prereq #378 Prereq #310
Define null tests that can be performed given the LSST cadence, deep drilling fields, colors, and ancillary data sets.
Evaluate existing software for two-point null tests.
Validate the DC2 mock lightcone galaxy (and maybe lensing) inputs for WL DC2 analysis. Generate new shears and magnifications for the input galaxy catalog as needed.

Determine required size and depth of simulations. This will involve estimating how accurately we will want to be testing the shear null tests, how many galaxies we will need to achieve this level of precision, what kind of tomography is required. These requirements should then be tranlated into size and depth requirements.

Develop the null test pipeline.
Define the null tests to be automated based on Stage III dark energy survey inputs.
Confirm that DM will be providing all the necessary metadata that we need for our null tests. e.g. various temperatures, wind speed and direction, etc. (This may be a very quick task, since I think they are already planning to provide all of these things and much more.)
Define null tests based on the mask information produced by \deliverableref D:CX-DC1-Mask-SW1 .
Develop systematics model for photo-z errors contributing to mis-identification of lens and source planes using the dataset from \deliverableref PZ2 .

Enhance and validate the null test pipeline, including automation.
Determine the most useful applied shear and convergence. (Ray-tracing through the DC2 light cone, Gaussian shears from a cosmological power spectrum, or something even simpler?)

Validate the null test pipeline with DC1 data and relevant pre-cursor data sets.
Collect a set of standard assumptions, based on the first year of LSST data, to be used in setting requirements, such as number density, sky fraction, and redshift/angular bins. Share these with the collaboration. Prereq #383 Prereq #3 Prereq #2 Prereq #1 Prereq #378 Prereq #310 Prereq #572 Prereq #383 Prereq #3 Prereq #2 Prereq #1 Prereq #378 Prereq #310 Prereq #572
