NAME
     pcql2ah - Convert PCQL seismic data trace files to AH format

SYNTAX
     pcql2ah [_o_p_t_i_o_n...] [_t_r_a_c_e__f_i_l_e...]

DESCRIPTION
     pcql2ah reads digital seismic data from the  specified  PCQL
     (UNOCAL  Corporation)  _t_r_a_c_e__f_i_l_es (standard input default),
     converts them to the XDR (External Data Representation) ver-
     sion  of  Lamont's AH (AdHoc) format, and writes them to its
     standard output.  Because the output is binary, it  must  be
     directed  to a file, device, or pipe, and not sent to a ter-
     minal.

OPTIONS
     The following  command-line  options  are  used  to  control
     pcql2ah.   Options  are  scanned from left to right; if con-
     flicting options are given, the  rightmost  one  takes  pre-
     cedence.   Only  enough characters need be given to uniquely
     identify an option.

     -help [_o_p_t_i_o_n...]
          Print brief explanations of the specified _o_p_t_i_o_ns.   If
          no  _o_p_t_i_o_ns are named, explanations are printed for all
          _o_p_t_i_o_ns.  The explanations are written to the  standard
          error output.

     -stafile _f_i_l_e
          Use the specified PCQL station  _f_i_l_e,  instead  of  the
          default.   The station file is used only to map channel
          numbers and dates into station and component codes; the
          station  coordinates  are  not copied to the AH header.
          Since there are different station files for  each  net-
          work,  you must specify the station file -- there is no
          default station file.

     -ahtype float|short
          Specify the output datatype for the AH data.  The short
          datatype  specifies  short  (16-bit) integers, and is a
          USGS extention to  Lamont's  AH  format.   The  default
          datatype is float.

FILES
     /data/dc1/unocal/parameters/f.stn - station file for F
     /data/dc1/unocal/parameters/g.stn - station file for G
     /data/dc1/unocal/parameters/w.stn - station file for W

     AH-format digital data.

EXAMPLES
     To convert the PCQL file 1090085b.g91 to AH format and store
     the result in the file 1090085b.g91.ah, use the command

          pcql2ah   -stafile    /data/dc1/unocal/parameters/g.stn
          1090085b.g91 > 1090085b.g91.ah
