It all depends upon what you want to do with this.  If it's just so  
you can come back and fit it another day, most people just usually  
write a load script that runs through the read the data/combine/flux  
correct procedures.  It rarely takes so long that saving the data  
really buys you much.

If it's a matter of saving that combined, flux corrected data in a  
file so that you can give it to a friend to fit in XSPEC, you're out  
of luck.  (You can, however, regroup and rebin data, and save that  
grouping to existing type I pha files, and your XSPEC friends can then  
fit the data with the binnings you've used.)

If it's a matter of saving the data that you plotted so you can then  
ship it to something like IDL, I do have routines that do that.  I  
have a bunch of plotting routines in my .isisrc files that have an  
associated function, "write_plot" that will do an ascii dump of the  
last thing you plotted, in simple ascii columns.  So, "plot_unfold(- 
[megm1,megp1];options...)" followed by "write_plot("meg_combined")"  
would give you combined, flux corrected data written to ascii files.

I've placed a tar'd, gzipped version of my .isisrc files at:

	http://space.mit.edu/home/mnowak/data/ISISRC

(note: they will upack to things like ./.isisrc, so make sure you  
don't overwrite your own stuff).   There are headers in those files  
listing the functions, and most functions invoked without arguments  
will return help messages.  But other than that, documentation is  
minimal.

Cheers,

Mike
