VLBEXPORT


VLBEXPORT can be used to extract data from a Merge-format  file  into  a
text   file  that  can  be  read  easily  by  other  programs,  such  as
spreadsheets and commercial plotting programs.  The output file has  one
record   (line)   per   uv-point,   with   comma-delimited  fields.   If
tab-delimited fields are required by the target program, a  text  editor
can  be used to replace commas with tabs.  No header information (source
name, station locations, etc.) is recorded in the output file.

Field 1: time UTC (modified Julian date) [days]
Field 2: baseline number
Field 3: amplitude [Jy]
Field 4: amplitude error [Jy]
Field 5: phase [deg]
Field 6: phase error [deg]
Field 7: u [millions of wavelengths]
Field 8: v [millions of wavelengths]
Field 9: w [millions of wavelengths]


Example

$ VLBEXPORT
INPUT  = T1.MRG
OUTPUT = T1.TXT
/


Parameters

Parameters INPUT and OUTPUT must be specified.  The parameters names can
be  abbreviated  to  uniqueness (minimum match).  All the parameters are
character strings, but they need not  be  enclosed  in  quotation  marks
unless  they include commas or blank spaces.  End the list of parameters
with a slash (/).

INPUT = "filename" :  the name of the  input  merge-format  file  (e.g.,
          INPUT   =  CITSCR:[TJP.B2]T1.MRG).   This  parameter  must  be
          specified; there is no default.

OUTPUT = "filename" :  a name for the text file  created  by  VLBEXPORT.
          This parameter must be specified; there is no default.


Limitations

The maximum number of stations is 20; otherwise, all  MERGE  files  with
format 1 or 2 should be acceptable.
