I'm out today - school is on spring break this week.
I'll take a look by tomorrow.

|    5    1331+305     -90   66      7      13,17,18,21,23,24,26

|   10    1415+133    -129   61      0
|   11    1130-148    -116   11      5      3,4,12,14,24

| the notable exception to things working is 3C286 - where most of the EVLA
| antennas failed.  i thought it might be because of a long slew or high
| elevation, but neither of those seem to be the case, so i'm a bit baffled
| by
| that failure.  but otherwise it looks pretty good.
|
| if things were calm today, we might want to ask the operators if they
| could run
| a longer pointing file during maint time, but the winds are already at 6
| m/s
| (max of 9 m/s already today), so it might not be worth it.
|
| but if vivek has a look at the results and sees reasonable things, then we
| should definitely ask for a real pointing run as soon as we can get it, to
| fix
| up 21.
