Solstice/Solistice

[Stobal]

Is there a good reason to use both "solstice" and "solistice" - with an i - unregularly as code variables, package listing and library file name? I think the correct word is without an i.

In Astro.Solistice.js source code all the function comments refer to "JDE of the March equinox for the given year." This is peanuts but by flyover reading one could accidentally pick a wrong function to use.

Cannot figure out why equinoxes and solstices here give about 1 - 1,5 minutes later times than the ones listed by Wikipedia.
