This code contains a library of routines for use of the CMC-14 star catalogue data. For information about CMC-14, see:
The library is written in C, despite the .cpp file extensions. Make files are provided for g++ in Linux, OpenWatcom C/C++, and Microsoft Visual C/C++. I'd expect the code to port readily to other systems, though it looks as if there may be problems (at least thus far) on "big-Endian" (non-Intel) systems.
Functions are provided to:
With these functions, it's possible to losslessly compress the 102-byte ASCII records of the "original" CMC-14 into 25-byte binary records, resulting in a roughly fourfold decrease in file size. This allows all of CMC-14 to fit in about half of a DVD (2 597 619 150 bytes). The code in cmc14xvt.cpp shows how the conversion is done.
An example of the use of the above function is given in extr_cmc.cpp.
