; Any line beginning with a ';' is assumed to be a comment. Any other ; non-blank line is assumed to be a possible JPL ephemeris file. Find_Orb ; first looks for ephemeris files specified in 'environ.dat', as described ; at http://projectpluto.com/find_orb.htm#de_eph ; ; But if you haven't specified a JPL ephemeris file, Find_Orb looks ; through this list. That lets you simply drop a JPL ephem file into the ; Find_Orb folder, and have Find_Orb figure it out on its own. ; ; The files listed are assorted JPL binary ephemerides found on-line or ; the Willmann-Bell CD, or distributed with Guide 8.0 or 9.0. Byte order ; is not a problem; the software will flip bytes as needed. ; ; If Find_Orb doesn't locate a JPL ephemeris file, it'll still run. It ; just may be noticeably slower in some situations. ; From the Willmann-Bell CD-ROM: ; -3000 to +3000, about 200 MBytes: unix.406 ; From the Willmann-Bell CD-ROM: ; 1600-2200: about 56 MBytes: unix.405 ; http://cococubed.asu.edu/codes/ephem/unxp1600-2200_ppc_mac_xlf.405 ; Same file as above, I think unxp1600-2200_ppc_mac_xlf.405 ; http://cococubed.asu.edu/codes/ephem/unxp1600-2200_intel_mac_ifort.405 ; Same file as above, I think, except reversed byte order unxp1600-2200_intel_mac_ifort.405 ; From the Guide 9.0 DVD: ; -3000 to +3000: about 557 MBytes: jpl_eph.422 ; Same file as above, under a different name, available at ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de422/lnxm3000p3000.422 ; (about 545 MBytes) lnxm3000p3000.422 ; Similar files from same site: ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de421/lnxp1900p2053.421 ; (about 13 MBytes) lnxp1900p2053.421 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de423/lnxp1800p2200.423 ; (about 37 MBytes) lnxp1800p2200.423 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de418/lnxp1900p2050.418 ; (about 13 MBytes) lnxp1900p2050.418 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de414/lnxp1600p2200.414 ; (about 55 MBytes) lnxp1600p2200.414 ;ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de405/lnxp1600p2200.405 ; (about 55 MBytes) lnxp1600p2200.405 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de406/lnxm3000p3000.406 ; (about 200 MBytes) lnxm3000p3000.406 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/de403/lnxp1600p2200.403 ; (about 55 MBytes) lnxp1600p2200.403 ; From the second Guide 8.0 disk: 1800-2200, about 13.3 MBytes: sub_de.406 ; ftp://ssd.jpl.nasa.gov/pub/eph/planets/unix/de406/unxp1800.406 ; Covers 1800-2100 (now renamed as shown above) unxp1800.406 ; http://adams.dm.unipi.it/~orbmaint/orbfit/JPLEPH/DE405_win.dat ; 1900-2060; about 14 MBytes (file size indicates it may cover more years) DE405_win.dat ; http://adams.dm.unipi.it/~orbmaint/orbfit/JPLEPH/DE405.dat ; 1970-2020; about 4.7 MBytes DE405.dat ; From the Willmann-Bell CD-ROM: ; 1600-2169: about 43 MBytes: unix.200 ; Recently (mid-2013) JPL created extra-long ephemerides.
