XMM-OM Search Output Columns


This document defines the catalog entries describing the XMM Optical Monitor Data Archive as delivered to MAST by HEASARC. Most of the documentation below was obtained from the the HEASARC Data Archive Center.

Archive Background:

XMM was launched by ESA on December 10th, 1999 and carries two distinct types of telescope: three Wolter type-1 X-ray telescopes with different X-ray detectors in their foci, and a 30-cm optical/UV telescope with a microchannel-plate pre-amplified CCD detector in its focal plane.

General Results Options

Most mission search results pages have the following general features/options. (Note that the sorting, paging and VOPlot options all require JAVASCRIPT to be supported and turned on, and the interactive plotting option uses HTML5 which is not supported in Internet Explorer before version 9.)

  1. Clicking on the column headings at the TOP of the results table will sort the returned results based on the selected field. Clicking the column heading a second time will sort the results in descending order. As of August, 2014 sorting is now possible with RA and Dec coordinates in sexigesimal notation, and the previous bugs whereby exponents are ignored in numbers using exponential notation (e.g., 6.3E-3 is sorted as if it were 6.3), and signs were ignored in floating point numbers have both been corrected. Note however that the sort functions (like many interactive features) are written in javascript which is not always supported in older browsers. Alternatively, selecting the sort options in the initial query does not depend on javascript, and will sort the entire search result, not just the displayed rows.

  2. Clicking one of the column headings at the END of the results table (or clicking the "columns help" link at the top of the page) will display help information about the search results page and the displayed columns (i.e., this page).

  3. By default, results are shown with 500 entries per page, with links to additional pages if more than 500 entries were returned. The number of rows per page can be modified using the "Records per Page" form element on the search form. The total number of entries returned is set by the "Maximum Records" value from the search page.

  4. One numerical column can be plotted versus another using VOPlot although see the Help page regarding issues with the latest version of Java.

  5. For some missions, thumbnail images of the returned entries can be displayed by clicking the link listed just below the VOPlot link.

  6. The mark column, as described below, can be used to plot spectra and download files. Plots are now interactive with added features.
