So JD=2000*365 is not the year 2000. You can use J2000, which is #defined to the JD of 1/1/2000. KSNumbers( J2000 ); long double jy; //jy is years since 2000 for ( jy=0.0; jy<10000.0; jy += 500.0 ) { num.updateValues( J2000 + jy*365.238 ); _______________________________________________ Kstars-devel mailing list Kstars-devel@kde.org https://mail.kde.org/mailman/listinfo/kstars-devel
