 gl2fit
        Task to convert GMRT LTA format data to FITS format.

 Programmer
        Vasant Kulkarni  (vasant@gmrt.ernet.in)
        
 in  
        Name of the input  LTA file.
        NO DEFAULT

 out  
	Name of the output FITS  file.  Note that program
        converts ALL LOWER CASE letters in the output file name to  
        UPPER CASE LETTERS. This an AIPS requirement.  
        NO DEFAULT

 dbgmode  An integer  to indicate the number of records to read in 
        each scan. If dbgmode is not set or set to zero all the records in
        each of the scans are read. If dbgmode is set to an intger, say, n 
        then only  first n records are read from each of the scans. This is  meant
        for program testing. For normal use LEAVE DBGMODE unset.
        DEFAULT  dbgmode off i. e. read all records. Note that the dbgmode
        parameter appears as one of the inputs only if you  start the program
        as follows:

        gl2fit help=dbg
        

 iat-utc Note that IAT-UTC=1.0n secs where n is an integer. Since
        Jan 1998 n=32 . The value of n changes usually in Jan
        or July (whenever a leap second is introduced in UTC to keep
        it within 1sec of UT1). Default ( iat-utc is left unset) is
        32secs.
        DEFAULT iat-utc=32

 writeself  An INTEGER. If writeself >= 1 write self correlator values.
              If writeself <=0 DO NOT write self correlator values.
              DEFAULT DO NOT write self correlator values.

 normalize  normalize >=1 use normalized correlation coefficients.
              normalize =0  use raw (unnormalized) corelation coefficients.
              DEFAULT ( normalize is left unset) normalize. 


 ampmax     Maximum value of amplitude allowed.
              if amp > ampmax then amp=ampmax and weight=-1.0.
              DEFAULTS
              normalized  mode   ampmax=1.0
              unnormalized mode  ampmax=1000.0

 ampmin     minimum value of amplitude allowed.
              if amp < ampmin then amp=ampmin and weight=-1.0.
              DEFAULTS
              normalized  mode   ampmin=0.0
              unnormalized mode  ampmin=0.0
