Hello! I'm trying to reproduce the DES Y3 cosmic shear results and I'm trying to make a Cobaya YAML file that follows what is specified in Table II, page 14 here:
I have looked at all the mcmc and evaluate yaml files in this repo and I don't seem to find the blocks where you sample the parameters "Lens redshift width 1" ($\sigma z _{l}^{1}$), which I believe in cosmosis are called lens_photoz_errors--width_1... etc.
The cosmosis chains I'm looking at are these:
des y3 cosmosis chains
I am including here the relevant cosmosis block with the width parameters that I cannot find in cocoa_des-y3 (the bias_1 parameter corresponds to what cocoa-desy3 calls DES_DZ_L1, correct?):

## [lens_photoz_errors]
## bias_1 = gaussian -0.009 0.007
## bias_2 = gaussian -0.035 0.011
## bias_3 = gaussian -0.005 0.006
## bias_4 = gaussian -0.007 0.006
## bias_5 = gaussian 0.002 0.007
## width_5 = gaussian  1.08  0.067
## bias_6 = gaussian 0.002 0.008
## width_1 = gaussian  0.975  0.062
## width_2 = gaussian  1.306  0.093
## width_3 = gaussian  0.87  0.054
## width_4 = gaussian  0.918  0.051
## width_6 = gaussian  0.845  0.073
