Show Periodic Table of the Elements, for choosen element
type the name, atomic number, atomic weight, melt and evaporation temperatures.
Script by: Matthew Hoesch (mdih@msn.com). 

For given geographical longitude and time zone
show the current data and time, Universal data and time, current local
star time. Possible to insert the summer time correction. 

Show the current month calendar, any month and any year
calendar is avaliable too. Script by: Rob Patrick (rpatrick@mit.edu). 

Accept 10 different data formats (data&time, data
with decimal day of month, data with decimal day of year, decimal year,
some Julian dates), calculate from any formate to others, show day of week.
Current data and time direct insertion function is exists. Correction for
time zone is avaliable. 

Calculate angular distance between two points at the
sky by its equatorial coordinates. Accept coordinates in h/m/s/deg/arcmin/arcsec,
degrees and radians, recalculates coordinates from any of this forms to
others. 

Simple program to transform equatorial coordinates from
any start epoch to any final epoch. Accept coordinates in h/m/s/deg/arcmin/arcsec,
degrees and radians, recalculates coordinates from any of this forms to
others. 

Similar to previous program, but also show the constellation,
in which point (with calculated coordinates) is placed. 

Similar to previous program, but also accept and calculate
the galactic coordinates in deg/arcmin/arcsec, degrees and radians. Also
recalculates coordinates from any of this forms to others. 

Similar to previous program, but also accept and calculate
for two epochs the ecliptic coordinates in degrees and radians. Also calculates
the ecliptic/equator inclination angle for the both epochs.
