We produced single-band IRAC1 and IRAC2 catalogs, measured aperture and integrated fluxes/magnitudes and corrected aperture fluxes/magnitudes using the correction factors adopted in SWIRE DR2 by

IRAC aperture radii [arcsec] - ap1 = 1.4 / ap2 = 1.9 / ap3 = 2.9 / ap4 = 4.1 / ap5 = 5.8

We did merge single-band IRAC1 and IRAC2 catalogs into an IRAC12 catalog using a search radius of 1.0 arcsec

We did add three columns at the beginning of the catalog

- ID_12 index to track sources (single-band indices are NUMBER_1 and NUMBER_2)

- ALPHA_J2000_12 and DELTA_J2000_2 which are average values for sources detected in both IRAC1 and IRAC2
