it concatenate files with names '1xAllWISE' or '12xAllWISE' or whatever, that are in a folder 'project', and then saves the result in 'project/ALL.dat'

Discussing cut of 0.5 in stellarity parameter to separate stars (>0.5) from galaxies (<0.5). Need to consult higher authority here.

• Good colour selection for brown dwarfs is the WI-W2 colour.
• Major contaminants in that colour is Dust obscured galaxies(DOGs) and Asymptotic Giant Branch stars.
• According to Spitzer data for AGB and DOGs. Their color are red in W1-W2 and red in W2-W3. However, brown dwars are red objects in W1-W2 but bluer in W2-W3. Therefore they suggest a cut W1-W2 <3.0.
