Need to fix obs:gotolonglat error

[CelestiaProject]

In Celestia 1.7.0 source code (even in the 5229 revision from SF), the error occurred: In CELX scripts where used obs:gotolonglat command, not processed distance parameter. The reason for this is unknown to me, but I think that error associated with porting the source code on a new mathematical engine Eigen.

Write in celx: obs:gotolonglat(Earth, math.rad(0), math.rad(30), 3.5004702E14, 5)
Celestia must go to Earth at a distance 3.5004702E14, but Celestia go to Earth center!
File: celx_observer.cpp
String 363: distance = distance / KM_PER_LY;
If comment this string, the Celestia go to Earth the correct distance.
