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…

A. Siemiginowska, G. Eadie, I. Czekala +49
Over the past century, major advances in astronomy and astrophysics have been largely driven by improvements in instrumentation and data collection. With the amassing of high quali…
Photometric Biases in Modern Surveys
Stephen K. N. Portillo, Joshua S. Speagle, Douglas P. Finkbeiner
Many surveys use maximum-likelihood (ML) methods to fit models when extracting photometry from images. We show these ML estimators systematically overestimate the flux as a functio…
