Title: Introduction of subtables in MeasurementSet Person responsible: Bob Garwood (bgarwood@nrao.edu) Originator of proposal: Tim Cornwell (tcornwel@nrao.edu) Exploders targeted: aips2-astro-design, aips2-gbt Time table: Date of issue: 1996 January 26 Done Comments due: 1996 February 2 Done Revised proposal: 1996 February 5 Done Final comments due: 1996 February 9 Done Decision date: 1996 February 12 Accepted Statement of goals: ------------------- - To simplify columns in MeasurementSet. - To allow MeasurementSet to store complicated sets of data such as that written by the VLBA correlator. - To define common format for both SingleDish and Synthesis data. Proposed changes: ----------------- In essence, subtables are to be used in place of many columns. Only the principal data (e.g. Visibilities) and various coordinate and index information are to be stored in the main table. The other information (eg antenna characteristics) is to be stored in subtables attached as table keywords. The MS is to be inclusive of information presented by a telescope. For more details of this proposal see here This proposal is accepted as is. We will implement a synthesis version and then make a final proposal based upon that experience.
