Search help

Use J2000 equatorial coordinates in either decimal or sexagesimal format and an optional search radius in arcminutes. The maximum search radius is 60 arcmin = 1.0 deg. If a search radius isn't specified, 5.0 arcmin will be used by default.

By default, results are returned in order of increasing distance (in arcsec) from the center coordinates.

Decimal coordinates
[DD]D.ddd... [+-][D]D.ddd... DD.dd...
example: 289.0 45.0 10.0
Sexagesimal coordinates
HH:MM:SS.sss... [+-]DD:MM:SS.sss... DD.dd...
HH MM SS.sss... [+-]DD MM SS.sss... DD.dd...
example: 19 25 27.9129 +42 47 03.693 15.0

Search help

Full text search is useful for object names, variable type tags, object classification tags, and external object names (e.g. from SIMBAD if they're available). Queries use the SQLite FTS5 query syntax.

For an exact match to an object name, use "object name".

To look up object names using the SIMBAD SESAME resolver, check the Look up object names using SESAME box. In this mode, you can also look up clusters and nebulae, etc. using their common names (Messier, NGC, etc.). The LCC-Server will then try to find all matching objects within a 1.0 degree radius centered on the reported SIMBAD coordinates.

Examples:
objects in ASAS and NSVS: ASAS AND NSVS
all ASAS objects at RA 19h: "ASAS J19"*
RR Lyr color EBs: simbad_best_objtype:EB color_classes:RR*

Search help

This form lets you build a query based on the available columns in the database and the filters you choose. Filters may be chained together using AND/OR logic. You may also choose a column to sort the result-set rows in a particular order. This will be automatically added to the requested query columns.

Examples:
proper motion > 200 mas yr-1 and r < 11.0
J - K > 2.0 and Stetson J variability index > 1.0
color class "RR Lyrae" and dereddened g - r < 0.3
