Catalogue Information

Copyright WDC C1 for STP at RAL.

These may be divided into two main classes: (i) operational details and (ii) phenomena. In addition, there are a number of catalogues which contain information about the database ("metadata" in database terminology). The operational details class comprises:

• Catalogue of data-taking periods - orbit number, date, start and stop times, name of the duty scientist for the period.

• Comments catalogue - log of comments recorded in control centre.

• Ephemeris - database of UKS position and velocity and its separation from IRM. The position and velocity of the IRM are also recorded - but only for the period of UKS operation.

The class of phenomenological catalogues includes:

• Regions catalogue - orbit number, date, region, period in region
• Boundaries catalogue - orbit number, date, boundary, time of crossing
• FTE catalogue - list of flux transfer events observed by the UKS magnetometer - gives time, location and polarity of the FTE.

The catalogues of data-taking periods, comments, regions, boundaries and the ephemeris were compiled by Peter A Smith at Rutherford Appleton Laboratory; the FTE catalogue was compiled by Mark Saunders and Richard Rijnbeek at Imperial College London. A very detailed description of all six catalogues is given in AMPTE DATABASE REGENERATION: Structure of UKS catalogues by M A Hapgood, RAL document number 92064PRO0155.

The metadata catalogues include:

• list of data files
• details of the fields in the data files - names, descriptions, units.
