Introduction
Before delving into data calibration, editing, etc., it is very important to understand the structure and contents of a measurement set (the format in which EVLA data are stored). These pages will guide the new user through loading and initial inspection of their data.
Currently, these Guides include information on loading and inspecting EVLA data, as well as on the structure and organization of the measurement set (MS).
If you are using AIPS to reduce your EVLA data please refer to Appendix E of the AIPS cookbook.
