Metacal catalogs

The metacal catalog is used in TXPipe for Dark Energy Survey catalogs from Y1 and Y3.

Each quantitiy is measured under 5 different conditions: the nominal measurement, and four variants that are used to calculate calibration factors that account for shear measurement and selection biases. The variants are labeled “1m”, “1p”, “2m”, “2p”.
