Examples

To convert a text file of about 10000 lines containing the columns X, Y and PIXEL VALUE into a basic HDS file.

  ICL> TEXT2HDS
  INFILE - Name of input text file > M33.DAT
  OUTFILE - Name of output HDS file > M33_IMAGE
  NCOLS - Number of columns in the text file > 3
  NROWS - Maximum number of lines in input file > 20000
  CNAME1 - Name of array to hold 1st column > XAXIS
  CNAME2 - Name of array to hold 2nd column > YAXIS
  CNAME3 - Name of array to hold 3rd column > DATA_ARRAY
Produces:

     M33_IMAGE.
               XAXIS(10000)
               YAXIS(10000)
               DATA_ARRAY(10000)
To convert the same file into an EVENT dataset

  ICL> TEXT2HDS EVENT OUTFILE=OUT
Produces:

  OUT                           
    .XAXIS                      
    .  .DATA_ARRAY(10000)       
    .  .UNITS                   =" "
    .  .FIELD_MIN               =  0.00000E+00
    .  .FIELD_MAX               =   9999.0
    .YAXIS                      
    .  .DATA_ARRAY(10000)       
    .  .UNITS                   =" "
    .  .FIELD_MIN               =  0.00000E+00
    .  .FIELD_MAX               =   9000.0
    .DATA_ARRAY                 
    .  .DATA_ARRAY(10000)       
    .  .UNITS                   =" "
    .  .FIELD_MIN               =  3.50000E+00
    .  .FIELD_MAX               =  512.400
If you have a SCAR descriptor file for the input file.

  ICL> TEXT2HDS SCAR EVENT
  INFILE - Name of input text file > M33.DAT
  DSCFILE - Name of SCAR descriptor file > DSCFM33.DAT
  OUTFILE - Name of output HDS file > M33_EVENT
