Create standard measurement sets for testing calibration

[danasimard]

We will need a few standard measurement sets to test calibration routines. These should include:

• a long observation at a high-declination field with a bright calibration gain/amp source for developing direction-dependent calibration (+82 deg)
• a field with multiple bright calibration sources to develop multi-source sky models and primary beam models for direction-independent calibration
• measurement sets for polarization calibration

Gregg suggests, for the high dec field, J2344+8226 (Aliases: 2344+824 B2342+8210 2342+821). RA: 23h 44m 3.772s Dec: 82° 26' 40.401". L band flux of 3.8 Jy

[danasimard]

At our current declination we have two datasets useful for developing the primary beam model and multi-source sky models:

• J141120+521209 is a 22 Jy source w/ 74 percent of the flux in the field, ideal for modelling the primary beam (and sefd measurements and azimuth pointing errors). In /mnt/data/dsa110/calibration/dana/60min/ there is a 60-minute measurement set on this source. The primary beam model for the dsa-110 can be fit to this measurement set.
• J033743+504552 is a 3.3 Jy source, with a 2.2 and a 1.2 Jy source also in the beam. J033743+504552 is approximately 1 degree off of the pointing declination, while the other two are ~ 1.5 degrees off of the pointing declination.
