FORMCONSTANTS(1)         TIPSY COMMANDS           FORMCONSTANTS(1)



NAME
     formconstants - set the constants related to star formation

SYNOPSIS
     formconstants cstar dtime temppar softpar

ALIASES
     fconst

DESCRIPTION
     formconstants sets the value of  constants  that  relate  to
     star formation for use in commands such as viewgas. The star
     formation algorithm is from Katz  (Ap.  J.  391:502,  1992).
     All  the  constants are in system units with G (the gravita-
     tional constant) equal to 1 and temperature in degrees  Kel-
     vin.

          cstar
             is the constant that is linearly proportional to the
             star formation rate.

          dtime
             is the time between calls to the star formation rou-
             tine.

          temppar
             is the constant that decides how cool the gas can be
             before the cooling time is ignored.

          softpar
             is the constant that decides when  the  Jean's  cri-
             teria can be ignored.
