Multiband Probabilistic Cataloging: A Joint Fitting Approach to Point Source Detection and Deblending
Richard M. Feder, Stephen K. N. Portillo, Tansu Daylan +1
Probabilistic cataloging (PCAT) outperforms traditional cataloging methods on single-band optical data in crowded fields (Portillo et al. 2017). We extend our work to multiple band…
