Find clusters of galaxiesCatalog level virtual dataTestbed design
Weak Lensing in the Southern SurveyWeak lensing from image shape parametersDrives construction of coadded image dataThe coadd is data intensive
Correlation FunctionsAuto and cross correlation of galaxiesCPU intensive, monte carlo testing more soWill break up galaxy sample into many sub-samples
High surface brightness/Low surface brightnessBlue galaxies/red galaxies
Saving and distribution of results at a premium
