I kept doing the same thing
today. I have succesfully transformed the magentic data to an array
that is the same as the holemap array. Although I have done this, I am
still having issues. Around the poles the transformation can contort
things a lot. As a result, when I try to fill in these contorted
contours the wrong parts will be filled in. As a fix I am eliminating
the magnetic data that is outside of the 80 degrees latitude in both
hemisperes.

Today I went
and watched the Borealis group launch their balloon with their
experiments attached to it. This took up the entire day so I will
continue working on the code tomorrow.

I am
continuing to work on my program. As soon as I get one part to work,
another part won't or I'll realize that I forgot to take something into
account. I have been contouring the open field regions using the idl
program contour. I then take the positions that it gives me I convert
them to POS coordinates. I then fill in these contours using
pollyfillv, another idl program. I'm getting closer but I am still
working out the kinks. I have to use part of the contour program to
individually select each separate open region so that when I fill in
the contours it is filling in the right areas. The way contour does
this is a little tricky so I am trying to get it to work successfully.

As has
become the norm, changing my program to do this was not as easy as
originally anticipated. At this point I should realize that there isn't
going to be an easy fix for anything. My goal is to create a mask for
both the coronal hole map and the open region map. The masks will have
1's where there are holes/open regions and 0's where they aren't. I can
then multiply them together in order to see where they overlap. These
masks should be in POS coordinates. The problem is that the two things
I am comparing don't work well together. I am working to convert the
open regions in longitude and lattitude coordinates to POS. This
conversion is the hardest part.

Today
I began figuring out how I can make changes in my program in order to
quantify my results better. Up until now I have been determining if the
coronal holes match up with the open field regions by sight alone. It
was brought to my attention that phrases like "they match up pretty
well" doesn't give a lot of information. Thus I have started to find a
way to find the percentage of coronal holes that overlap open field
regions.
