q12 
allwise_sc2 
WISE 
Correlation significance between W1 and W2. The value is log10(Q2(rho12)), where Q2 is the twotailed fraction of all cases expected to show at least this much apparent positive or negative correlation when in fact there is no correlation. The value is clipped at 9.

4 



When the number of measurements is large, the significance of correlation also tends to be large even though the correlations themselves may have a small magnitude. This is a typical manifestation of statistical significance increasing as the sample size increases; eventually the significant effect can be due to small correlated errors in background estimation or even roundoff errors. These effects tend to be small but become significant when there are enough observations of them. High flux correlation significance should be taken seriously only when the magnitude of the correlation is also fairly high. 
q23 
allwise_sc2 
WISE 
Correlation significance between W2 and W3. The value is log10(Q2(rho23)), where Q2 is the twotailed fraction of all cases expected to show at least this much apparent positive or negative correlation when in fact there is no correlation. The value is clipped at 9.

MCPS 
Quality flag (unique sum of the following flags): 0 = no flag; 1 = star for which photometry was replaced with that from Massey's catalog (Massey P., 2001, ApJS, in press); 2 = star for which photometry was replaced with that from OGLE; 10 = star with a successful stellar atmosphere model (Χ²<3) fit; 20 = star with an unsuccessful stellar atmosphere model fit.
