times in the stella code itself use t=0 at start of run.
but the output from stella_extras are at times since Lbol max.
typically there is no stella output for the times since breakout when we want to see results.
so the code has to interpolate between the available stella data snapshots.
the output times are determined by the calls on save_day_post_Lbol_max starting at line 458.
for example, if you want to get interpolated results for 33.7 days post Lbol max, then insert a new line between the ones for output at 30 days and at 40 days. the final arg to save_day_post_Lbol_max is a string that goes in the filename - you need to change that as well.

The "stella/strad/run/mesa.dat" file which controls all the other STELLA outputs does not seem to affect these, and whatever the default is gives fairly sparse data at early times. Is there another file which can be used to control the Fe II velocity outputs?
