.short initial input profile

[SahaAnirban007]

Pardon me if the question is trivial. I am new to Fortran. How can I create/get the .short initial input profile used in Collapse simulations?

The details for this are in the user guide: https://github.com/evanoconnor/GR1D/blob/master/docs/README.pdf in section 3.

GR1D uses the '.short' format for input stellar profiles. On
the first line of the input file is the number of lines in the input
file. The rest of the file consists of lines with 8 columns each: (1)
zone index, (2) enclosed mass (g), (3) radial coordinate (cm), (4)
temperature (K), (5) density (g/cm^3), (6) radial velocity (cm/s),
(7) Ye, and (8) \Omega (rad/s).

The README also references an example which I have just added to the repository in the profiles directory. As none of the supernova progenitor files are published/released by me, I don't want to post them here, but from the description and the example, it should be clear what you need to do to make one. You don't need to know any fortran, a simple bash/python script can be used to make these files.
