Monitoring the Lensed Quasars FBQ 0951+2635 and SDSS 1650+4251 in the Near-Infrared: Technical Challenges
Abstract
We present two seasons of J- and H-band imagery of the doubly-lensed quasars FBQ 0951+2635 and SDSS 1650+4251 taken using the ASTROCAM infrared imager on the 1.55m Kaj Strand Reflector at the US Naval Observatory (USNO), Flagstaff AZ. The data were taken as a component of the US Naval Academy (USNA)-USNO lensed quasar monitoring program, whose primary objective is the use of quasar microlensing to constrain the physical properties of the quasar continuum source. In this investigation, the brightness of the blended multiple images are deconvolved from the flux from the lens galaxy using a variety of techniques including point-spread function modeling and difference imaging in an effort to pick to most reliable technique for our data reduction pipeline.
