13 I (Johannes Gajdosik) have just taken Valery Laineys Fortran code,
14 MarsSatV1-0.f, which he kindly supplied, and rearranged it into
15 this piece of software.
16 
17 I can neither allow nor forbid the usage of Valery Laineys
18 Ephemerides of the Martian satellites.
19 The copyright notice below covers not the work of Valery Lainey
20 but just my work, that is the compilation of Valery Laineys
21 Ephemerides of the Martian satellites into the software supplied in this file.

44 My modifications to the "Ephemerides of the Martian satellites" as implemented
45 in MarsSatV1-0.f are
46 1) do not calculate constant terms at runtime but beforehand
47 2) unite terms with the same frequencies
