Sample Selection

 

 

  We select our list of target calibrator fields from the VLA calibrator manual which met the following criteria:

 

S20 cm > 0.5 Jy and

 

I      The source should be (a) a P-class at A-array and B-array VLA configurations, and (b)

        either a P-class or a S-class at C-array and D-array VLA configurations (121 sources).

II     The source is either a P-class or a S-class at A-array or B-array VLA configurations (301).

III    Rest 250 sources in VLA calibrator manual.

 

 

I       The source should be a S-class at A-array VLA configuration at 90 cm (77 sources).

II      The source should be a S-class at B-array VLA configuration at 90 cm (Rest 51 sources).

III     Rest 34 sources in VLA calibrator manual at 90 cm.

 

 

 

  From this list, we are presently focussing on the first 121 (priority I) sources at 20 cm.
