NAME
formconstants - set the constants related to star forma-
tion
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
gravitational constant) equal to 1 and temperature in
degrees Kelvin.
cstar
is the constant that is linearly proportional to
the star formation rate.
dtime
is the time between calls to the star formation
routine.
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
criteria can be ignored.
