Here is a simple tutorial for exporting NEWSTAR FITS

    Step-by-step procedure: from e.g. ASTE telescope to CLASS
     1. The ASTE telescope will produce output data in the raw NEWSTAR format.
         You will probably get a DAT tape with all NEWSTAR fits files.
         e.g. rawdata file name:    n1068
     2. start NEWSTAR
     3. in NEWSTAR: read in the DAT tape (use task FROM_CMT with parameter
         "1-99", set the tapedrive name, and execute FROM_CMT).
     4. in NEWSTAR: use task LINTEG/SPFits to write out each raw NEWSTAR file for
         one filterbank at a time. i.e. specify the input rawdata file from the
         previous step and an output file name, check the box "indiv scan", check
         one filterbank (i.e. A1, A2, A3, A4) at a time, then execute task.
         e.g. you will now have n1068a1.fits n1068a2.fits n1068a3.fits n1068a4.fits
     5. Use procedure NSCLASS.PRO to read in the NEWSTAR fits files produced
         in the above step, and output CLASS compatible fits files. For help
         on this step, see below.
   6a. Use the CLASS procedure file generated by NSCLASS.PRO to read in
         and consolidate the fits files produced in the previous step.
         e.g. you will now have one output file, "n1068.bur", which contains
         all scans originally in the raw NEWSTAR file "n1068".
   6b. Start IRAF (change loginuser.cl to include the line
         set imtype      =fits
         so that IRAF will work directly with FITS files.
   7.   Proceed with processing in CLASS or IRAF.

EXAMPLE USAGE OF THIS PROCEDURE:
       IDL> .rnew NSCLASS.PRO
       IDL> NSCLASS,'myinputlist','CO(3-2)','myoutputlist','classread.class'

       'myinputlist' : contains a list of NEWSTAR fits files written with SpFITS.
                           one file per line. E.g. contents of file <myinputlist>:
                               n1068a1.fits
                               n1068a2.fits
       'CO(3-2)'     : this is the name of the transition observed.
       'myoutputlist': is an optional file which contains file names for the output
                             fits files. Each input file corresponds to n output files, where n
                             is the number of scans in the input fits file.
                             E.g. if each input fits file consists of 10 scans, then
                             the file 'myoutputlist' should contain 20 lines, as follows:
                             n1068a1_0001.fits
                             n1068a1_0002.fits
                                      ...
                             n1068a1_0010.fits
                             n1068a2_0001.fits
                             n1068a2_0002.fits
                                      ...
                             n1068a2_0010.fits
                        There is no restriction in the name of the files, as long as you
                        have one file per scan.
                        The program will then output fits files named as above.
                        If file <myoutputlist> does not exist, or is empty, then default
                        extensions are used for the output fits files; these consist of the
                        input name followed by "_sc0001" etc. E.g. output files
                            n1068a1_sc0001.fits
                            n1068a1_sc0002.fits
                                     ...
                            n1068a1_sc0010.fits
                            n1068a2_sc0001.fits
                            n1068a2_sc0002.fits
                                     ...
                            n1068a2_sc0010.fits
       'classread.class': this file will contain a class procedure to read in
                                   and consolidate all fits files produced by NSCLASS.PRO.
                                   To run it, enter CLASS (part of GILDAS) and at the prompt type:
                                   LAS>  @classread.class
                                   e.g. you will now have the files n1068a1.bur and n1068a2.bur.
                                   n1068a1.bur will have all scans originally in the raw NEWSTAR
                                   file n1068a1, and the same applies to n1068a2.
