Hi Paul,

I have just pushed an updated version of tesseral force model in the git
repository, prior to 7.2 release. This version adds configuration
parameters for short period terms, these parameters are available
in the tutorial as new keys.

I did not find any parameter, even hard-coded, in Orekit implementation
that would correspond to LTSHAN, but I am not sure.

The mapping for currently available customization parameters should be:

 max.degree.zonal.short.periods                          NZN
 max.eccentricity.power.zonal.short.periods              LZN
 max.frequency.true.longitude.zonal.short.periods        JZN

 max.degree.tesseral.short.periods                       NTS
 max.order.tesseral.short.periods                        MTS
 max.eccentricity.power.tesseral.short.periods           LTS
  ... nothing here ...                                   LTSHAN
 max.frequency.mean.longitude.tesseral.short.periods     JMAXTS

 max.degree.tesseral.m.dailies.short.periods             NMD
 max.order.tesseral.m.dailies.short.periods              MMD
 max.eccentricity.power.tesseral.m.dailies.short.periods LMD

Could you pull this version on your computer and check if everything
looks fine to you? The customization changes did modify some
ancillary data of the tests (size of the ephemeris, number of
short periodic terms stored). It appeared a few parameters were
overriden in some parts of the code, this may explain these changes.

I will wait some time before publishing version 7.2.

best regards,
Luc
