Comparison between the point source catalog generated by the WFCAM pipeline (based on aperture photometry) and the sources detected and measured in this work by performing PSF fitting photometry, for the R08 object SSTGLMC G048.8731−00.5091. Left: UKIDSS GPS H-band image, overlaid with the positions of the point sources from the UKIDSS catalog. Middle: the same image overlaid with the positions of the objects detected by our PSF fitting photometry. Right: residual image of the PSF fitting photometry, i.e., after subtraction of scaled PSFs at the positions of the detected sources.
