MARKSTAT(1)               TIPSY COMMANDS              MARKSTAT(1)

NAME

       markstat - print physical parameters of marked particles

SYNOPSIS

       markstat box particle

ALIASES

       mstat

DESCRIPTION

       markstat  prints  physical parameters of the marked parti-
       cles in box box-number for the marked  particles  of  type
       particle.   Parameters  that are listed are: the mass, the
       density, the volume of the box, the size of the  box,  the
       center  of  mass coordinates, the center of mass velocity,
       and the angular momentum per unit mass in  the  center  of
       mass  frame.   This  is similar to the boxstat command but
       only for the marked particles.

       Particles can be  marked  using  the  markarray,  markbox,
       markgal,  and  readmark  commands. Marked particles can be
       written to a file using the writemark command.

       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.

       If no particles are marked or if  box  box-number  is  not
       loaded an error is generated.

                 Show the physical parameters of only the  marked
                 gas particles.

              star
                 Show  the physical parameters of only the marked
                 star particles.
