ESASky Search formats

SEARCH BY TARGET NAME OR COORDINATES

The ESASky search accepts many different types of names and coordinate formats. Below there are some examples of accepted formats. Note that, for coordinates, a '+' or '-' sign is needed before the declination. Both equatorial or galactic coordinates are accepted; to input galactic coordinates, the 'galactic' frame must be selected in the top-left corner of the application. For solar system objects an ID number is also accepted.

Target Name examples:

M 31
m101
crab nebula
Jupiter
mrk421
Churyumov-Gerasimenko
69P
arcturus
Sgr A*
sn 1006
vela x-1
puppis A

USAGE WITH A TARGET LIST

For now, names of Solar System Objects are not resolved in a target list.

Coordinates are interpreted based on the coordinate frame selected when the target list is uploaded; this will not change if the coordinate frame is changed at a later stage. Sexagesimal formats are only resolved in equatorial J2000 coordinates.

SEARCH BY AUTHOR OR BIBCODE

It is also possible to do a search by author name or bibcode, as in the examples below:

Hubble H
Rubin V
1953ApJ...118..353H

This is not possible with target lists.
