Re: Ensemble photometry

Mike,

Yep, I am interested.  I have some 4 x 4 degree test areas that I would
like to run through the program.  The one I am currently running contains
380,326 measurements of 12572 stars.  You can find this file in mike at
/home/tom/cal_files/test/work1 as 300:6:tr0.  This is two years of data
taken between ra of 300 to 304, dec +6 to +10.

What I would really like is for you to run it through the program and make
a plot of mag vs sigma for the data.  Like the ones I have recetly been
posting.

Eventually I would like to run the following combinations:

droege/gp
ensemble
droege/gp then ensemble
ensemble then groege/gp

This implies that the output format is the same as the imput format.  That
is when you run the 300:6:tr0 file through any of the processes, you get a
file with the same number of lines with the same line elements that has
somehow been made better.

Of course, all are welcome to play this game.

Also of interest is the time it takes to run each pass of each version.

For any method that shows promise, I would then like to run the a sequence
of different declinations.  There is also a file of on mike
/home/tom/call_files/test/300:304:tr that contains all declinations
between 300 and 304 ra that can be broken up to get different decs.
