SHARC-II without chopping to observe all our sources. In this mode the telescope moves in a Lissajous pattern that keeps the central regions of the maps fully sampled. Beyond this region of uniform coverage, the integration time per position decreases smoothly from the center outward. According to information presented on the SHARC-II webpage[^3], this mode works best for sources with sizes less than or comparable to the size of the array. During all of our observations except those obtained in June 2005, the Dish Surface Optimization System (DSOS[^4]) was used to correct the dish surface figure for gravitational deformations as the dish moves in elevation during observations. For the June 2005 observations, an equipment malfunction caused the DSOS to correct all observations for a zenith angle of $49\mbox{$^{\circ}$}$ (where the zenith angle is defined to be $90\mbox{$^{\circ}$}-\mathrm{elevation}$), regardless of the actual zenith angle of the observations. The effects of this on our results are discussed in §\[results\].
