Day 49

Tuesday.  Slacking off on the astroph.  Must ... turn ... brain ... on ...  I want to generate an MEF so that I can to get SExtractor working with it, then with SCAMP.  Then report to Gary!

Precision simulation of ground-based lensing data using observations from space
Mandelbaum, Hirata, Leauthaud, Massey, Rhodes


SHERA (SHEar Reconvolution Analysis) simulates ground-based data, starting from space-based images from COSMOS (CTE-corrected images used), and taking into account the HST PSF.  Optionally apply weak lensing shear.  Allows for a precise, realistic assessment of systematic errors due to the method of data processing, given user-suppled observational conditions and real galaxy morphologies.  Can also test error estimates and parameter degeneracies.  Software publicly released.


* Good job Rachel!
