As I explained, the solar pulse is a near-constant. The nine digits given are derived as the average SSB pulse for the 73 main stationary points from 1500-2099 (defined as period between similar wave peaks and troughs). These pulse points are almost all within one year of my magic number, with a quarter of them within 0.1 years. The source is NASA JPL ephemeris, which I understand is very precise and accurate for this dataset. I will analyse the data to quantify the rate of change in this number since 1500.
