Extract mean data for a list of objects

Give the name of your file of object names :

The ASCII file, created on your computer, must contain one designation per line (a designation can specify the nearest object to a given celestial position, which allow an easy positional cross-identification, see doc). See an example of query list

Select output parameters below and then "submit" above
