Therese,

 

I would trust the Solar Fire calculations to agree with CCRS within a

few seconds, more or less. I haven't used Nova in years. And I don't

remember how ingress or returns compared to CCRS. Sorry.

 

I've uploaded comparison charts for the Kobe Quake in 1995. I

included both the CapLunar and CanLunar ingresses, as I don't think

separating the lunar ingresses give a true comparison of the tools

used. Since the quake was only a couple days after the ingress, I

have not included Q1 progressions.

 

I'll work on the other quakes as I get time, and I'll comment on your

other post on the SF Fire & Quake later.

 

Sidereally yours,

Matthew
