How far can we use multi-wavelength cross-identifications to deconvolve
far-infrared images? In this short research note I explore a test case of CLEAN
deconvolutions of simulated confused 850 micron SCUBA-2 data, and explore the
possible scientific applications of combining this data with ostensibly deeper
TolTEC Large Scale Structure (LSS) survey 1.1mm-2mm data. I show that the
SCUBA-2 can be reconstructed to the 1.1mm LMT resolution and achieve an 850
micron deconvolved sensitivity of 0.7 mJy RMS, an improvement of at least ~1:5x
over naive point source filtered images. The TolTEC/SCUBA-2 combination can
constrain cold (<10K) observed-frame colour temperatures, where TolTEC alone cannot.
