\textit{\textbf{Tile definition}} \section{Tile definition}
Stripe 82 (-50 to 59d, -1.25 to 1.25d) will be observed in four "squashed" tiles, 30d x 2.66d:
...
Because each tile is 30d long, a reasonable option is to divide each squashed tile into two or three "sub" tiles, each 10x2.66 or 15x2.66d. The two sub-tiles of 15x2.66d should probably only be considered if good phase calibrators can be found right in the middle of the two-sub tiles. This is unlikely, so three sub-tiles of 10x2.66d is the likely design. Each sub-tile can have its own phase calibrator, and the full observation will move along the tile, one sub-tile at a time. Whether to start with the easternmost or westernmost sub-tile will depend on whether the full tile will be observed rising or setting.
\textit{\textbf{Resources}} \section{Resources}
- the NRAO calibrator list ("P" calibrator in both L and C band if possible, close to tile, bright in L and C band)
...
- Steve/Kunal have previously used J2212+0152, J2323-0317 (close to satellite belt), J2247+0000. I think J2212+0152 is good for a couple of these, but J2323-0317 is fainter than the one I suggest below, and S code in L-band. Could get info from Kunal. J2247+0000 is not in VLA calibrator list, so would need info from Kunal.

\textit{Stripe \textbf{\textit{Stripe 82-A: 300 to 330d, -1.33 to
1.33d} 1.33d}}
- Sub-tile 300 to 310d: only reasonable choice I find is J2011-0644: P-code in L/C, ~1.5Jy. All others within 15d of center are S-code and faint. Major downside is this is further south, in/toward satellite belt...

(Could potentially do a 15d mini-tile from 315 to 330d, with super-bright J2136+0041, 1.8d from 322.5+0d, but there's no good calibrator for a sub-tile from 300 to 315d)
\textit{Stripe \textbf{\textit{Stripe 82-B: 330 to 360/0d, -1.33 to
1.33d} 1.33d}}
- Sub-tile 330 to 340d: J2212+0512, P-code in L/C, ~1-2Jy (<3d from center)
...
- Sub-tile 350 to 360/0d: J0022+0014, P-code, ~1.5Jy (10.6d from center); could use J0016-0015, 0.8Jy
\textit{Stripe \textbf{\textit{Stripe 82-C: 0d to 30d, -1.33 to
1.33d} 1.33d}}
- Sub-tile 0d to 10d: very good one J0022+0014 (same as previous sub-tile)
...
- Sub-tile 20d to 30d: J0059+0006 (same as previous sub-tile)
\textit{Stripe \textbf{\textit{Stripe 82-D: 30 to 60d, -1.33 to
1.33d} 1.33d}}
- Sub-tile 30d to 40d: not
an obvious one. obvious. Only one P-code in L/C: J0259+0747, 0.85Jy, 12.5d from center. Others have a P-code in C-band and an S- or X-code in L-band. We could observe
some of the potential ones in S-band
ourselves to try to find calibrator.
- Sub-tile 40d to 50d: J0259+0747
