Specifying reference values in TGLF/CGYRO input files

[bpatel2107]

Would it be possible to add in the ability to optionally store the normalising reference values in standalone CGYRO/TGLF input files to allow for easier conversion to SI units. That or maybe a supplementary file which specifies these.

Ideally we'd want to store
$n_{e}$, $T_{e}$, $B_{unit}$, $a$ and optionally $m_{ref}$

When running with an input.gacode file these are specified in the out.cgyro.info file so there is some capability already.

Good question. FYI, Emily and I generally encourage users to not run with input.gacode but instead to generate a local input file using the -loc_rad option of profiles_gen. Also, for experimental modeling TGYRO is better suited for computing the local gyrobohm factors and target fluxes. The original motivation for a separate tool (profiles_gen) to manipulate profile data was to separate the GK calculation from the profile manipulation. I think generation of a supplementary file is the better option that might even allow us to remove the information from out.cgyro.info. How about generation of the supplementary file using profiles_gen -loc_rad ?

[bpatel2107]

Yeah I think that would be fine. Something like a out.cgyro.units would work great for most purposes.

OK, I'm fine to move forward with this.

For my two cents, I think it would be great to add to the out.cgyro.units, but would really like to keep the information in out.gyro.info<http://out.gyro.info> as well. I find a lot of utility in running of input.gacode directly, and think that workflow has some advantages for avoiding mistakes when dealing with many different experiments or sets of profiles. Happy to discuss further next week when back from IAEA.
