Long Period Variables

[Tom Droege <tdroege2@earthlink.net>]

I have completed the first pass of data analysis on the 4 degree grid 
data.  This ongoing survey takes images on a 4 degree grid once a night.  I 
cover from -6 to +18 degrees.  So far I have 3 Million measurements of 
about 600,000 stars with many stars having of order 10 measurements.

Just for fun I ran the data through WS and got 50 candidates with WS over 
100.  Most look like short period variables of one type or another.  Just 
noise or dips indicating eclipsing binaries.

I looked at these and picked out 3 that appear to be long period 
variables.  I found one listed in the GCVS, the other two I did not 
find.  But I seem to have problems using Visier.

107.7751  	+4.0767	WW CMi
112.6539	+15.5735
125.5065	+13.6181

Note that this data should contain a lot of Landolt stars.  I await someone 
who wants to study the quality of the color transformations.
