This document defines the catalog entries describing
the SIITARCHIVE Data Archive.
General Results Options
Most mission search results pages have the following general
features/options. (Note that the sorting, paging and VOPlot
and the interactive plotting option uses HTML5 which is not
supported in Internet Explorer before version 9.)
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.
that the sort functions (like many interactive features)
Alternatively, selecting the sort options in the initial query
and will sort the entire search result, not just the displayed
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 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.
One numerical column can be plotted versus another using VOPlot
although see the Help page regarding issues
with the latest version of Java.
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. Plots are now interactive with added features.
Clicking on this box will mark the entry for retrieval.
For missions with proprietary data, the mark button element
will have a yellow background and a '@' symbol to indicate
data sets not yet public.
The selected datasets will be downloaded in a single file.
You may select the file type: .tar, .tar.gz, .tar.Z, and .zip.
After selecting the file type, click on the "Download selected files" button
and the selected files will be downloaded to your disk.
After selecting up to 15 observations to be plotted, click on the "Plot marked spectra" button
to coplot the selected observations.
The spectra that you selected will be automatically scaled to the full range of wavelengths and
nearly the full range of fluxes (i.e., y axis plot scale runs from 0 (or .25 * the minimum flux
for spectra with negative fluxes) to the 10th highest flux). Each spectrum is automatically
assigned a color, up to a maximum of 15. The spectra are labelled by their dataset names, with a
summary of the datasets plotted given below the plot. After inspecting the plot, you may wish to
change the selection of datasets which are displayed. Use your browser "Back" button to do this.
Plot range Adjust the minimum and maximum wavelengths (in ┼ngstroms) and minimum and maximum fluxes (in erg
/cm2/sec/┼) to select the spectral region of interest and to exclude noisy data.
Plot dimensions Adjust the X size and Y size in pixels to create the size of plot desired. The maximum dimensions ar
e 850 by 640 pixels.
Redraw plot Use this button to replot the spectra when you have changed the plot range or plot dimensions.
