Description détaillée

Almanach et publication astronomique en langue anglaise.

Ouvrage en version papier.

This almanac contains positions of the Sun, polaris and selected bright stars in a form which is convenient for land surveyors who use astronomical'observations to détermine their geographical position or direction to true north. This edition includes a CD-ROM which contains the almanac in pdf format and the coefficients representing the positions of the Sun and stars in ASCII files. ASCII data files are available on the CD-ROM which contain coefficients for calculating the Greenwich hour angle and d'clination of all the stars published in The Star Almanac, accurate to about 1 arcsecond. The polynomial coefficients for calculating R (GHA Aries - UT), d'clination, E and semi-diameter of the Sun are also included.
