Binned catalogs

Binned catalogs are split with each tomographic bin having its own HDF5 group.

They can also include calibrations, applied such that they can be used directly in 2pt calculations or other science measurements.

Binned shear catalogs

The tomographically binned shear catalogs also include the shear calibration to correct for measurement and selection biases.

The bin index b runs from 0 to nbin-1, or “all” tag for a combined non-tomographic sample. The “all” bin is not simply the same as all the other bins combined, because the selection bias calibration is different.

Like the original source shear catalogs, the binned shear catalogs may include only a subset of magnitude values depending on what was measured during the pipeline. An example using riz bands is shown below.

Group		Name	Kind	Meaning
shear	bin_{b}	ra	1D float64
shear	bin_{b}	dec	1D float64

shear	bin_{b}	mag_i	1D float64
shear	bin_{b}	mag_z	1D float64
shear	bin_{b}	mag_err_r	1D float64
shear	bin_{b}	mag_err_i	1D float64
shear	bin_{b}	mag_err_z	1D float64
shear	bin_{b}	weight	1D float64

Binned lens catalogs

There are two classes of binned lens catalog, weighted and unweighted. The latter includes a varying weight to account for survery property density correlations. In the former the weight is unity.

The final weighted catalog should be used for all science measurements.

The bin index b runs from 0 to nbin-1, or “all” tag for a combined non-tomographic sample.

Group		Name	Kind	Meaning
lens	bin_{b}	comoving_distance	1D float64
lens	bin_{b}	dec	1D float64

lens	bin_{b}	mag_err_r	1D float64
lens	bin_{b}	mag_err_u	1D float64

lens	bin_{b}	mag_z	1D float64
lens	bin_{b}	ra	1D float64
lens	bin_{b}	weight	1D float64

Binned random catalogs

The binned random catalogs match the tomography of the lens sample. Two random binned catalogs are generated, one with a much smaller sample size, suitable for use when measuring the density-density correlation, and a larger one suitable for measuring the lensing-density cross-signal. The smaller catalog has the suffix “_sub”.

Group		Name	Kind	Meaning
randoms	bin_0	ra	1D float32
randoms	bin_0	dec	1D float32
randoms	bin_0	comoving_distance	1D float32
randoms	bin_0	z	1D float32

Binned star catalogs

Binned star catalogs are not tomographic, but instead split into classes used differently in systematics tests. Currently that means two bins, “bright” and “dim”.

Group		Name	Kind	Meaning
stars	bin_bright	dec	1D float64
stars	bin_bright	ra	1D float64
stars	bin_dim	dec	1D float64
stars	bin_dim	ra	1D float64
