Calculation of Tidal Deformability Uses Detector Frame Masses in EOS Routines
Named EOS and parameterized EOS functions in LALInference (and Bilby) are passing the detector frame masses and not source frame masses when calculating the tidal deformability. E.g. see blocks of code here and here. Using source frame masses in code will require assuming a fixed cosmology in order to perform the conversion.
Issue has been raised on Mattermost chat by @cjhaster here and in separate email thread with: @patricia-schmidt, @katerina.chatziioannou, @cjhaster, @john-veitch, @jocelyn-read, @tim.dietrich.
