KODIAQ Archive: Documentation

To search an area on the sky, provide the center location and search radius:

Center: Enter a coordinate string or object name (must be resolvable into coordinates by NED first then SIMBAD). Coordinate strings with no equinox specified will be treated as J2000. Note: If an equinox year is provided, but is not preceded by either a Bessel "B" or a Julian "J", the year will be ignored and J2000 will be assumed. The search field is case-insensitive.

Examples:
  UM673
  26.31921 -9.75481 eq
  01h 45m 16.61s -09d 45m 17.3s Equ J2000
  161.63962 -68.47971 gal

Radius: The default search radius is 1 arcmin
