Query Setup (usage)

Maximum Entries per table:

Output layout:

Output Order:
+ -

Query by Position on the Sky (Adapt Form to use a List of targets)

Target Name (resolved by Simbad) or Position:

Position in Sexagesimal, or Decimal °

Target dimension:

Radius or Box size

Output preferences for Position:

	r	x,y	Position	Galactic	J2000	B1950	Ecl.J2000	none
