Gauss method appears unsuitable #1

After attempting to implement the Gauss method for preliminary orbit determination in Mathematica (Dimitri) and Python (me), it seems that it can't cope with such short arcs.

Potential alternatives are being actively explored - incl. the idea of performing an optimization process using TLEs.

For testing: need to get lst info from the relevant frame headers and parse to gauss.py. Then have enough to find position vector and can feed real data into algorithm.

Tested with various cases:

textbook examples working fine
realistic params for some of our longer time interval cases
very bad results with shorter timescales Thus for most of our objects we need a better method.
