[Mesa-users] Surface gravitational acceleration units?

[Aaron Dotter]

In the top lines of history_columns.list it says:

! history_columns.list -- determines the contents of star history logs
! you can use a non-standard version by setting history_columns_file in
your inlist


*! units are cgs unless otherwise noted.*
and there you have your answer.
