Revision 1767cceaa7edbc0db626de61a6124f73c64e162e authored by Francesco Pannarale on 30 June 2023, 10:45:21 UTC, committed by GitHub on 30 June 2023, 10:45:21 UTC
* Space before colons in eos_utils.py help messages * Enable extrapolation in eos_utils.py when NS is out of bounds * Same check on shape in primary_mass and secondary mass * Function to swap masses and spins of object 1 and object2 * Allow user to request for remnant_mass calculations: 1) extrapolation, 2) swapping object 1 and object 2 if mass2 > mass1, 3) treat as a (dark) BBH and NSBH with NS mass greater than a value probided by the user * Renamned swap_companions to ensure_obj1_is_primary and generalized it * codeclimate * codeclimate * Fixed line that was too long * Fixed docstring and using keywords explicitly in all remnant_mass_* calls * Renamed max_ns_mass as ns_bh_mass_boundary and improved help messages of functions * Improved docstings * Comprehensions in pycbc_brute_bank * Complying to naming convention for spin components in spherical coordinates * Update conversions.py Fixing single code climate complaint.
