C.3 Data set assumed in this Appendix

This appendix assumes a VLBA-only data set observed at several frequency bands (e.g., 1.6, 2.3, and 5.0 GHz). To include data from the non-VLBA antennas see §C.10. It is also assumed that phase-referencing programs have been observed according to the philosophy discussed in detail in VLBA Scientific Memo No. 24. The hypothetical observation considered here contains the following sources:

•  ‘CAL-BAND’ — fringe-search and bandpass calibrator
•  ‘CAL-AMP’ — amplitude-check source
•  ‘CAL-POL’ — polarization position angle calibrator
•  ‘STRONG’ — strong target source
•  ‘CAL-PHASE’ — phase-reference source
•  ‘TARGET’ — weak target source, to be calibrated with CAL-PHASE
