Y1A1 Mass Maps

Details on the production and testing of the original Y1A1 Mass Maps using Spherical Kaiser-Squires, can be found in Chang et al. (2018). Users should see that paper for any questions about the content of the original maps. The shear catalogs and photo-z catalog used for these maps are described in Zuntz et al. (2018) and Hoyle et al. (2018), respectively.

The file names are in the format of

y1a1_spt_${shear_cat}_${zmin}_${zmax}_${type}.fits

shear_cat: the shear catalog used, can be either mcal (metacal) or im3shape
zmin: the minimum redshift (BPZ mean z)
zmax: the maximum redshift (BPZ mean z)
type: E-mode kappa map (kE), B-mode kappa map (kB) or the binary mask used to construct the map (mask)

Note that each fits file contains one column named ${type} -- a 1D Healpix arrays with NSIDE = 1024 resolution and RING format.
