3. Parameter list
[Parameter lists are read in LibLoft/Manager/creadParam.f.]
In this appendix, explanation of all parameters available in the param file is listed. The parameters are classified in two categories named &PARAM and &HPARAM as found in the param file. The former is for a standard use while the latter is for a special use. The parameters are read as namelist of FORTRAN. Header files defining these variables are found under CosmosX/LibLoft/Header/ZincForNameL.h. Some general rules of the description are
Separator between values can be either a space or a comma.
Comment out is defined by a ‘!’ at the first column of a line.
If two values are given when a single value is requested, the first value is ignored.
