problems with eps files and pylab

Hi! I hope I have what is a simple question:

I recently created a figure using pylab and saved it using:
pylab.savefig(r'c:\fig3b.pdf',dpi=150)
and it worked great. I made the same figure with a .png ending and it
also worked well.

However, when I tried to make an eps file for use with latex and
publishing, I found:
using gsview:

DSC Error at line 527
%%Page: 11
This %%Page:line occured in the trailer, which is not legal.
EPS files should be encapsulated in %%BeginDocument/ %%EndDocument
It is possible that an EPS file was incorrectly encapsulated and that
we have been cofused by the %%Trailer in an EPS file

If I ignore all DSC, then I see a figure with noticeable gridding
across it. However, if I use distiller to convert it to a PDF file,
it appears fine.
Any ideas?

Thanks,
William
(the files are rather large, but are available at:
ftp://ftp.ncnr.nist.gov/pub/
as fig3b.ps, fig3b.pdf, fig3b.png)

Where is the eps file?

fig3b.ps

Is what I generated, using savefig. Does this generate postscript, or
eps output? If I changed the extension in savefig to, ".eps" would it
generate an eps file?

Thanks,
William

.ps is postscript, .eps is encapsulated postscript. Yes, you need to
specify .eps if you want an eps file.

ok, so, the file I generated is ".ps", so why is the gridding occuring?

Thanks,
William
