Gamma Serpentis (star)/meta

Notes (2016)

NOTE CONCERNING STAR POSITIONS:

When comparing real-astronomical star positions to the Traveller Map of Charted Space, it needs to be observed that the axes of the Charted Space Map appear to be tilted almost exactly 45^o counter-clockwise from the correct position (i.e. "true" Coreward actually lies parallel to the Lesser Rift). If one makes that adjustment, about 70% of the named stars will fall roughly along their correct bearing. However, there are some exceptions in which the star in question lies in roughly the correct position relative to the Charted Space Map without the need to rotate the coordinate axes.

In general, if one is assigning the position of a Real-Universe star to a Traveller Map hex, it should be acceptable if:

1) The star's longitude angle (θ) is within a 45^o bearing-arc between the "true" coordinate axes and the Traveller Charted Space Map coordinate axes, and

2) The star's assigned distance from Terra on the hexmap falls somewhere between its true distance R in parsecs, and its 2D-projection onto the flat map as seen from above, found by D_proj = {R * cos(ɸ)}, where (ɸ) is the latitude angle. If desired, the distance above/below the plane can be determined by Z = {R * sin(ɸ)}.

TRAVELLER NOTE:

A reasonably good fit for Gamma Serpentis would be the world Sebasta/Dingir (Solomani Rim 0923), which orbits a F4 IV star system at roughly the correct bearing and distance.

2300 AD NOTE:

In the 2300 AD RPG by GDW, Gamma Serpentis is the home star system of the Kafers.
