Subroutines, C Version 2.0.1."

NOVAS provides the core routines for star, planet, sun, and moon positions. These
same routines are used in MICA and to produce the Nautical Almanac published by
the United States Naval Observatory.

The latest JPL ephemeris, created in May-June, 1997. DE405 is based upon the International
Celestial Reference Frame (ICRF), the newly-adopted reference frame of the International
Astronomical Union (IAU). The frames of DE200 and DE405 differ by no more than about
0.01 arcseconds.

The Bright Star Catalogue (BSC) is widely used as a source of basic astronomical
and astrophysical data for stars brighter than magnitude 6.5. The catalog contains
the identifications of included stars in several other widely-used catalogs, double-
and multiple-star identifications, indication of variability and variable-star identifiers,
equatorial positions for B1900.0 and J2000.0, galactic coordinates, UBVRI photoelectric
photometric data when they exist, spectral types on the Morgan-Keenan (MK) classification
system, proper motions (J2000.0), parallax, radial- and rotational-velocity data,
and multiple-star information (number of components, separation, and magnitude differences)
for known nonsingle stars.
The BSC contains 9110 objects, of which 9096 are stars (14 objects catalogued in
the original compilation of 1908 are novae or extragalactic objects that have been
retained to preserve the numbering, but most of their data are omitted).

Although Pocket Stars does not use the positional calculations found in this book,
it is invaluable as a general text on astronomical calculations.

Not as comprehensive as Meeus, but valuable as an alternative approach which is
more methodical with step-by-step solutions to astronomical problems.
