Cross-correlations with galaxy surveys, this one focused on DES, but should be forkable to other analyses

Show level of foreground bias for baseline analysis choice

msyriac opened this issue · comments

The baseline analysis choice is (currently):
T_X = ACT+Planck tSZ deprojected
T_Y = ACT+Planck
kappa ~ asymmetric grad(T_X)T_Y+grad(T_Y)T_X coadded with all other non-TT estimators involving T_Y, E_act, B_act
lmin = 100
lmax_T = 3000
lmax_P = 5000

We will run this on simulations either from Sehgal et al or WebSky with and without tSZ+kSZ+CIB, and show what the bias is, if any.

You can also subtract out a CIB map for Planck by scaling e.g. the 545 GHz map

Also, worth finding out what is the timescale for getting tSZ and CIB maps from Buzzard (instead of using Websky/ Sehgal)
