Explanation of the figures showing IPN localizations.  
____________________________________________________



Date in upper right-hand corner: DD/MM/YYYY when the plot was produced.

Date and time above the upper right ascension axis: GRBYYMMDD and
the approximate time in seconds of day for the burst.  This time
is actually a fiducial time used for triangulation, and it may
differ from the Earth-crossing time by up to minutes in some
cases.

Right Ascension, Declination: these are J2000.  Not all the
figures are to scale; in some cases, changing the aspect
ratio displays the IPN error box more clearly.

Green lines: annuli obtained by triangulation.  These are
3 sigma confidence regions.

Green asterisk*: this is used to show the center of an IPN annulus,
when the inner radius is zero.

Black lines labeled "ECLIP."*: ecliptic latitude band, from
Konus-Wind.  These are generally ~90% confidence regions.

Black asterisk*: this is used to show the north or south ecliptic
pole, when the ecliptic latitude band extends to one of the poles.

Earth-N*: Earth-blocking, as seen from satellite N.  This region
is excluded from the localization.

Mars*: Mars-blocked, as seen from Mars Odyssey.  This region is
excluded from the localization.

Circles labeled GBM, LAT, Swift, AGILE, IBIS*: localizations obtained by 
the Fermi GBM, LAT, Swift-BAT, SuperAGILE, or INTEGRAL-IBIS.

Green shading: the region that is common to all the IPN annuli
and the ecliptic latitude band, but which excludes Earth- and
Mars-blocked regions.
