Tips & Tricks based on original UGC8201 star cluster candidates

Candidate #60 
=================================
We agreed to ignore the 3-4 stars that are relatively close to #60 and to treat this as its own isolated cluster candidate.  Thus, this would be a Class 2 and not a Class 3.

Candidates #32-#35
=================================
Dave agreed that we should likewise treat all 4 of these candidates as separate entities.  Do not consider them to be "contaminating each other" and thus perhaps Class 3.  Here are my classifications:
32 = 2
33 = 2
34 = 1
35 = 2

FWHM Threshold for star vs cluster
=================================
My rule of thumb was:
FWHM<2.2 ---> star (Class 4) 
and 
FWHM>2.2 ---> cluster (Classes 1,2,3).  
However, each image/camera/filter might slightly differ.  The best way to determine the threshold is to move your mouse around and hit 'r' on small compact sources that you think are stars, all across the image.  I did this for several stars in the 555 filter image for UGC8201, and here's what I found:
(x,y)=(1266,2920): FWHM=2.26
(x,y)=(1494,2955): FWHM=1.94
(x,y)=(1165,2735): FWHM=1.99
(x,y)=( 851,2698): FWHM=2.17
(x,y)=(2658,3600): FWHM=1.87
In summary, I believe my rule of thumb for 2.2 being the threshold was basically correct.  

Color Images
================================
There are jpegs in each directory that you should be able to use to help classify the trickiest cases.
