LEDA documentation: homogenisation
Homogenization of astronomical parameters

Introduction

LEDA has been the first Extragalactic Database. It was created in 1983 at Lyon Observatory. Since this time, the database has been continuously updated. The main idea is to collect raw measurements (coming directly from observations) and to archive them. Mean homogenized data are then calculated in the spirit of the famous series of Bright Galaxy Catalogues (RC1, RC2, RC3) by de Vaucouleurs and co-workers. In fact, RC3 was created using the LEDA database.

Examples of SQL searches

The SQL selection is very intuitive. Some of the following examples will help you to perform your selection : For a reference about SQL language, see the Postgres manual (HyperLeda uses Postgres DBMS). Note also that the SQL request can as well be submitted with POST or GET methods (the latter may be particularly useful to write scripts, for example using wget).

Calculation of homogenized astrophysical parameters.

For each parameter the method of the calculation (or the definition) is given in the Third Reference Catalogue (de Vaucouleurs et al., 1991) and/or in Paturel et al. (1997) and/or in some additional references given below. The "actual uncertainty" of parameters is defined in Paturel et al. (1997).
This table presents the references.
