The par is structure type defined in 2D-DDCC program. It saves the regional input parameters read in by input file. Therefore, it's value should roughly the same as the input expect some modification to the unit (Mostly converted into cgs unit)

Declear type(MODPAR) :: PAR

The PAR has following variables defined by type (MODPAR) , I didn't list all of them
