Problem with HST.f90 and using only Sn data.
Posted: July 03 2021
Hi everyone,
1. I want to constrain a model for dark energy using only the background data, e.g. supernovae data. How can I use paramnames_background.paramnames file? Since Ωbh2 and Ω_ch2 have not been included in this file, I fixed both the omega_b.h2 and omega_c.h2 values and left the range for the derived parameter Ω_m in params_CMB.derived_ranges unchanged. Unfortunately, I'm not able to produce contours (even for LCDM) for H_0, Ω_m and ΩΛ like what we see for A. Reiss. Am I missing something here?
2. If I use HST dataset, should I change HST.F90 file for my time dependent dark energy equation of state w=w(a)? It looks like this likelihood is merely for LCDM.
Any help would be appreciated.
