Error: `file (redshift not monotonic)`

[karenperezsarmiento]

Hello, I would like to use the six lens tomographic bins of the DES Y3 data. I made a new mask for this purpose using a script similar to the one here. However, once I attempt to run MCMC, I get this error:

file (redshift not monotonic)

I think this is related to the fact that I did not edit the nz_lens_file (I'm still using nz_lens_Y3_unblinded_final.txt file). How can I go about making changes to this file if I want to use the 6 lens tomographic bins?

This is what my .dataset file looks like:

data_file = Y3_unblinded_final.txt

cov_file = cov_unblinded_final.txt

mask_file = 3x2pt_nozcuts.mask

nz_lens_file = nz_lens_Y3_unblinded_final.txt

nz_source_file = nz_source_Y3_unblinded_final.txt

lensing_overlap_cut = 0.00

lens_ntomo = 6

source_ntomo = 4

n_theta = 20

IA_model = 6

theta_min_arcmin = 2.5

theta_max_arcmin = 250.
