Hello world. I am Brian.
The following corresponds to the h-band data. The j-band data can be found on
Hunter's webpage.
Hunter's webpage
The following link gives some general info concering the h-band data that may
be useful.

The following is a file containing a copy of how we initially read in each raw image.
Raw Image Read In
===================================================================
RING DATA:
- Arrays used for j-band South radial profiles. Arrays:
urbotfin, urbotfin_avg
- Arrays used for j-band North radial profiles. Arrays:
urtopfin, urtopfin_avg
- Arrays used for h-band North/South rings.
Arrays:
avgarray (averaged images from various sets of images), rotarr (rotated images
to be subtracted from the avgarray images), avgdiff (rotarr subtracted from
avgarray images)
- Arrays used for h-band North/South radial
profiles.
Arrays: avgmedtop (final averaged image from avgdiff for inner North
ring profile), avgmedbot (final averaged image from avgdiff for inner South
ring profile), outertop (array of images to be averaged for North outer rings),
outerbot (array of images to be averaged for South outer rings),
outerring (final averaged image for outer ring profile)
- Arrays used for k-band North/South inner/outer radial
profiles.
Arrays: rotarr (rotated images to be subtracted from the avgarray
images, topkarr (images used for North inner rings), botkarr (images used for
South inner rings), topkarravg and botkarravg (averaged images for North/South
inner rings), avgdifftopk and avgdiffbotk (rotarr subtracted from topkarravg
and botkarravg), outertopk and outerbotk (images used for North/South outer
rings), outerarrmed (averaged image for North/South outer rings)
Radial Profiles:
- Night 1 North Profile (h-band)
- Night 2 North/South Profile (h-band)
- Night 3 North/South Profile (h-band)
- VLT North/South Profile (h-band)
- Outer Ring North/South Profile (k-band)
- Outer Ring (North and South combined) (k-band)
- Night 1 North/South Profile (j-band)
- Night 2 North/South Profile (j-band)
- Night 3 North/South Profile (j-band)
- VLT North/South Profile (3 nights combined) (j-band)

The following links are .sav files containing the reduced images that are
corrected for exposure time. Each contains the array of images under the
filename and the median average of those images under the name filename_avg,
e.g. exh118 and exh118_avg. Note that the averages for exh388_1 and exh388_2
have the names exh388_1avg and exh388_2avg.

The following links are .sav files containing the reduced images that are not
corrected for exposure time. Each contains the array of images under the
filename, e.g. urh118, and the median average of those images under the
filename_avg, e.g. urh118_avg. Note that for urh388_1, the image array is
named urh388 with the average urh388_avg, and for urh388_2, the image array is
urh388_2 and the average image is urh388_2avg.

urcenters.sav is an array of the centers for each set of images in the order
that the links appear, e.g. urcenters(*,0) is the center of Uranus in each
image of the array urh118/exh118 and in urh118_avg and urcenters(*,18)
corresponds to urh488/exh488.
urcenters.sav
If you should find it useful to have a single array with all 263 h-band images,
you can download nights.sav, which contains all images in the array nights
(note that this takes a while to load). The images in nights are shifted so
that the center of Uranus is at urcenters(*,0). Similarly, the images for each night
are located in the arrays night1, night2, and night3.

The following are some of the prcedures we used throughout the process.
I will soon try to update the program info. in each file to describe what each
program does.
avgshift.pro
deprob.pro - Mate's deprojection program
urcenter.pro - to find center of Uranus
radialdist_2.pro - to generate arrays
that give the distance in pixels, km, or arcseconds form a given point
The following are some final plots that we generated. Coming Soon.
