\textbf{\textit{COSMOS: 145 to 155d, 0 to 8d}}  Actual COSMOS field is only about a square degree in size, located at 150.12d, +2.21d.  We are currently working to determine where is safe in the sky to look with regards to RFI. Basically, over the equator and various southern cities bring a lot of RFI when we look at low declinations near transit. To avoid: try looking at large hour angles (either positive or negative, far from transit). Steve points out that looking west over the Pacific Ocean generally is better than looking east, meaning that it's probably better to observe at high (positive) hour angles, as these low-declination tiles are setting.  For COSMOS, choice of using 3C286 while tile is setting, or 3C48 while tile is rising. Either way, we can get to about a 3.5-hour hour-angle limit (\sim30d elevation) for the lowest declination of the tile. While the tile is transiting, from basic setup looks like we could be observing at declinations as low as \sim3.5d. That might still be too low, so better to restrict it. Note that we'll be observing at transit with an elevation of \sim60d.
