1. If you want to use the data display option, you must be logged into a solaris machine.

2. Log into osiris as dbacker; cd to /gbpp0/mpulsar/gbpp/onlingbt

3. Script DOGBPP2  will start log window as well as the control GUI.

4. On the PC, if the 85-3 system is running, stop the loop with CTRL-C / Yes

5. On osiris, in /gbpp0/mpulsar/gbpp/onlingbt, do the 'cleanup' script

6. If re-booting the PC,  
	cd c:\97feb\data

7. On the PC, Execute:   'gogbt1'

8. In the Solaris directory (/gbpp0/mpulsar/gbpp/onlingbt)
   make sure appropriate dossified versions of 
   polyco.dos, ty.dos, and  rfif**   are present.
   Here ** refers to the different center frequencies.
   These files must be carefully constructed to tell the GBPP what RF
   comes to it at IF = 400 MHz. If creating new file, be sure it is
   dosified with unix2dos.

9. Type the desired source name in the GUI, and short cal (0 seconds)
   and integration times (30 sec). 
   Note that stop time is not used.

10. Press 'Start' on GUI.

11. Wait for the PC to go into observing loop, then press 'stop',
    wait for PC to go into waiting state.
    What is going on is that GUI creates an 'obs.bat' file 
    which the PC sees across the net.  The PC copies this across, 
    executes and then deletes the file.
    The GUI understands when file is deleted to complete handshake.

12. Select desired RF setup file in GUI which creates the generic
    'rfif.tbl' file.

13. Press 'UpdAll' to update polyco.dos, ty.dos, and rfif.tbl.

    or

    Press 'Update' to only update the RF setup by copying rfif.tbl.


14. Enter the source name and desired cal and integration times.

15. Press 'Start'

16. To end the observation, type 'Stop', 
    or if you want to end quickly, 'Abort'.

17. If the RF setup does not change, you can just enter a new
    source name and press 'Start' again.

18. Press 'refresh' to see latest scan files under 'recent scans'

19. To make a plot of a recent scan, select it in the GUI.

20. To dismiss the plot, type CNTRL-C in the xterm that came up 
    just before the plot.
