MARKGAL(1)                TIPSY COMMANDS               MARKGAL(1)

NAME

       markgal  -  mark  gas  particles  that are likely to be in
       galaxies

SYNOPSIS

       markgal box-number max-temp min-rho

DESCRIPTION

       markgal marks all the gas particles in box box-number that
       have  temperatures less than or equal to max-temp and have
       densities greater than or equal to min-rho.  This  command
       can be used to mark those gas particles that are likely to
       be in galaxies.  Marked  particles  appear  green  in  all
       plots.   Particles  in  a  particular  box can be unmarked
       using the unmarkbox command and all the  marked  particles
       can  be  unmarked  using the unmarkall command.  Particles
       remain marked even when a new time  frame  is  loaded  but
       after  a  new time frame is loaded any particles that were
       marked in the previous time frame  can  only  be  unmarked
       using the unmarkall command.

       Particles can also be marked using the markarray and mark-
       box commands.  Statistics about marked  particles  can  be
       determined  using  the  markstat command. Marked particles
       can be written to a file using the  writemark  command  or
       read from a file using the readmark command.

       If the box box-number is not loaded an error is generated.
