Detailed Description of the Data Product

This product contains the peak catalogue either based on a shear catalogue using mass aperture or convergence maps using wavelets.

This output product is composed of a FITS peak catalogue, and a description of the envelope of the sky area a with polygons (see spatialFootprint here).

Peak Catalog (First Extension, Binary Table)

1. EXTNAME = “PEAK_CATALOG”

The catalogue should contain the following columns:

Column name	Description	Unit
RA_OBJ		NA
DEC_OBJ		NA
ZMIN		NA

THETA		NA
SNR		NA

1. RA_OBJ: right ascension of the peak [D, float64]

2. DEC_OBJ: declination of the peak [D, float64]

3. ZMIN: minimum redshift of the bin where the peak has been detected [E, float32]
