... Science . ... The Local Sphere of Influence (LSI) survey is a deep near-IR (H-band) survey of galaxies residing in the Local Sphere of Influence ( D < 10 Mpc). The images with a typical surface brightness limit 4 mag fainter than 2MASS (24.5 mag arcsec -2 < SB lim < 26 mag arcsec -2 ) have been obtained with IRIS2 on the 3.9~m Anglo-Australian Telescope. 11 of the observations have resulted in non-dections or the images were saturated by foreground stars. ...
