This code archive has been generated on Thu Mar 15 12:26:26 CET 2012 ======================================================================== This directory contains the different components for generating the manuals required for traditional celestial navigation. Ageton: contains the code to generate simplified tables suited for the process of sight-reduction Corrections: here is the code for generating the tables used to "correct" the sextant altitude and convert it to a geo-centric comparable value. Interpol: the tables for perfoming interpolation required to obtain the correct values for GHA and Declination from the Nautical Almanac as well as for interpolating the calculated Altitude obtained from pre-calculated sight-reduction tables. JPL: this directory contains the basic ephemerides. Read the HOWTO/README files to find out how to download and generate the required files! NAlm: contains the code to generate the NAutical Almanac for a specified year. The compiled code needs the basic ephemerides data of the JPL/ directory! Novas: here is the original code of the novas software package. It contains some interesting background information on the available functions. Scripts: has some sripts for c-shell and bash shells SightRed: this contains the code for generating the pre-computed tables for the sight-reduction process. Each of the above sub-directories containing C-code are organized as follows: A subdirectory "src" comtains the source code, which can be compiled by typing "make" in the directory in which the "Makefile" is available. This will result in an executable file. The generated data are saved in the "Data" subdirectory. In case of trouble with the above stuff, please send an email to: 'erik.de.man@freenet.de'
