Low-Precision Ephemeris
- Coefficients for low-precision planetary ephemerides did not match paper or JPL website referenced in documentation. Not sure where original numbers came from. Some plantes (e.g., Mercury) matched. Others (e.g., Mars) did not, although numbers for Mars did match a google search. Very strange ... regardless, update so they match. Coefficients for years 1800 to 2050 AD are correct and remain unchanged.
- Add Pluto as a planet for low-precision ephemerides (it is included in reference paper, but not JPL website)
Two-Line Element Sets
- Fix issue where two-line element sets confuse satellite name for a line number if satellite name starts with a "1" or a "2"
