*********** release of 0.15.0 20120428 julian_day.c Removed not-needed BSD_SOURCE define Petr Kubanek 20120111 utility.c: utility.h: julian_day.c: Fix problems with double redefinition, pointed by Lukasz Michalik Petr Kubanek *********** release of 0.14.0 20110730 airmass.c: Added ln_get_alt_from_airmass function doc/doxyfile.in,doc/doxyfile Generate input doxyfile from doxyfile.in Petr Kubanek 20090917 sidereal_time.c: Fix problem with double transformation of degrees to hours, pointed by Edward Falk *********** release of 0.13.0 20090514 heliocentric_time.h: heliocentric_time.c: test.c: Added heliocentric time corrections calculations. Petr Kubanek 20090420 julian_day.h: Removed "#ifndef __WIN32__" to make ln_get_date_from_timet function available in win32 ln_types.h: Changed tv_sec type from long to time_t to match standard definition Clarified field documentation for ln_nutation julian_day.c: Removed "#ifndef __WIN32__" to make ln_get_date_from_timet function available in win32 Remove platform-dependent code form ln_get_date_from_sys. The function now simply makes a call to gettimeofday() - a Win32 implementation is supplied in utility.c, and this function is no longer limited to one-second precision under Windows. nutation.c: Fixed two values in nutation coefficients table Fixed method used to compute longitude/obliquity offsets. The general form of the calculation is supposed to be, e.g., coeff*sin(D+M+MM+F+O), not coeff*(sin(D) + sin(M) + sin(MM) + ...) Added correct computation for mean ecliptic (Meeus eq 22.2) (These fixes also fix ln_get_apparent_sidereal_time, and affect: ln_get_solar_equ_coords ln_get_solar_ecl_coords ln_get_equ_from_ecl (possibly needs true ecliptic rather than mean) ln_get_ecl_from_equ (possibly needs true ecliptic rather than mean) ) utility.c: Fixed gettimeofday Win32 implementation: should not add timezone offset - _ftime_s and gettimeofday both work in terms of seconds since Jan 1 1970, UTC Added some explicit casts to remove compile warnings Cleaned up implementations of ln_deg_to_hms, ln_rad_to_hms, ln_deg_to_dms, and ln_rad_to_hms patch provided by Kevin Ivarsen, applied by Petr Kubanek 20090323 Fixed issues while compling on Sun/Solaris (acosl, round, ..)
