Help: Coordinate Converter

Purpose

Coordinate Converter converts astronomical coordinates from one system into another.
 

Input

• Coordinate System: Can be any one of:
  
  1. Equatorial (2000): Equatorial coordinates with an epoch of 2000
  2. Equatorial (1950): Equatorial coordinates with an epoch of 1950. Note that many older catalogs are in B1950 coordinates.
  3. Galactic: Galactic coordinate system with l = 0 at the center of the Galaxy.
  4. Ecliptic (1950): Ecliptic coordinate system centered on the Earth with the ecliptic plane as b = 0.
• Input format is flexible. The separator can be spaces or commas:
  
  1. Two parameters for decimal degrees: RA or longitude in degrees (0 - 360); Declination in degrees (-90 to +90)
  2. Six parameters: Hours, minutes and seconds for each of RA and Declination or longitude and latitude.
• Output Coordinates: Same choices as input coordinates.
• Calculate button (or Enter): Performs the conversion.
• Clear button: Clears the Coordinates Box.

 

Results

Given in both degrees and hours, minutes, and seconds.
