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 turned on.):
- 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. Note that a bug currently exists
whereby exponents are ignored in numbers using exponential notation
(e.g., 6.3E-3 is sorted as if it were 6.3). Since most tables
don't include exponential numbers this is not felt to be a major
problem.
- 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).
- By default, results are shown with 50 entries per page, with links
to additional pages if more than 50 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.
(Note that when the total number of returned rows is
a multiple of 50, an extra page is displayed with no entries.)
- One numerical column can be plotted versus another using VOPlot.
- For some missions, thumbnail images of the returned entries
can be displayed by clicking the link listed just below the VOPlot link.
- The mark column, as described below, can be used to plot spectra
and download files.
