Method Detail

read

EphemerisTable read(String fileName)
                    throws IOException

Creates an ephemeris table from the data found in the given file.

Parameters:

fileName - the name of the file that has the ephemeris data.

Returns:

a new ephemeris table based on the data in the given file.

Throws:

IOException - if anything does wrong while reading the file.

read
