NAME
     std - standard star search

SYNOPSIS
     std [search] [display]

DESCRIPTION
     std is a command-line tool which allows to browse an  inter-
     nal  database  of  infra-red  standard  stars.  std contains
     internally a database of more than 800  stars,  built-up  by
     J.G.Cuby.  From  the catalog, it is possible to select stars
     based on a position criterion, name, sky region,  or  magni-
     tude in a given band.  Results can be displayed in different
     formats.

SEARCH OPTIONS
     Search options are related to  different  user-defined  cri-
     teria  to select a number of stars in the database. The fol-
     lowing are implemented:

     -p/--pos HH MM SS HH MM SSorDD DD
          If this is the only search criterion  on  the  command-
          line,  only  the  closest star to this position will be
          returned.  The  position  can  be  provided  as  hours,
          minutes,  seconds for RA and DEC (6 values expected) or
          simply in degrees (2 values expected).

     -r/--radius value
          Together with the --pos option, this specifies a radius
          around  a  sky  position.  All stars within this region
          will be selected.

     -n/--name value
          To search stars by name. The provided value is a  regu-
          lar expression, all stars matching it will be selected.

     -m/--mag band min max
          To search stars by magnitude  range  in  a  given  wave
          band. Supported wave bands are: J, H, K, Ks, L, Lprime,
          M, Mprime. Minimum  and  maximum  magnitudes  define  a
          range into which all stars are selected.

DISPLAY OPTIONS
     -k/--key
          To display the output in keyword format.

FILES
     The star database contains the following informations  about
     stars (in this order):
     Name of the star
     RA and DEC in HH:MM:SS format
     Spectral type

     Magnitudes in J, H, K, Ks, L, M.

EXAMPLES
     To print out the closest star  from  position  '10  12'  (in
     degrees):
     std --pos "10 12"

     To print out all stars within 10 degrees of this position:
     std --pos "10 12" --radius 10

     To print out all stars which name matches "FS*"
     std --name "FS*"

     To look for all stars in band L having a magnitude between 5
     and 6:
     std --mag "L 5 6"

BUGS
     It is not yet possible to combine selection criteria.
