===Per-feature parameters===
Each of these uses an independent number N.  If a feature is present it '''must''' have a feature''N''lat and a feature''N''long; the others are optional per feature.  Numbers should start from 1 and not skip any for best results.
* ''feature''N''lat'' - the latitude of the feature (can be one or three numbers like the others)
* ''feature''N''long'' - longitude
* ''feature''N''name'' - the main purpose of the name of the feature presently is to be a ''Wikilink''; apart from linking to an article this shouldn't be provided.  There might be a way to distinguish mouseover from the link in the future...
* ''feature''N''image'' - overrides the default [[:File:Full Star Yellow.svg]] with a filename you specify.  Omit File: from the parameter.
* ''feature''N''size'' - overrides the default 15px size for the image.
* ''feature''N''text'' - suppresses placement of any image - instead this arbitrary text is used.  This can be a link or not, and is displayed with upper left corner at the ''latitude'' and ''longitude'' you've provided.  The purpose is to allow annotation of general features or groups of features.  It can also be used to add a caption to a star on the map, by displacing it a little to the right (larger longitude) or in some other direction.
