Anchor bolt o.c. spacing— earthquake retrofitting

I am trying to order some Simpson retrofit foundation plates and can’t figure out what o.c. Stands for in the table that tells you anchor bolt size, diameter of screw
Here is the context:
Anchor bolt o.c. spacing
Also in the chart that tells you allowable loads DF/SP (160) there are two columns F1 and F2. Not sure what that stands for
Thank you so much!

O.C. is "On Centre". It tells you the spacing of the bolts. So every two feet would be 2'-0" oc.
DF is Douglas Fir. SP is Spruce-Pine
User-7039450,
Malcolm is correct. In Canada, o.c. stands for "on centre."
In the U.S., however, o.c. stands for "on center."

Below is an illustration that shows what F1 and F2 refer to.
The illustration comes from this Simpson catalog page: "Retrofit Foundation Plates."

You may want to read this Simpson guide: "Seismic Retrofit Guide."
On page 18, you'll find the handy guide to abbreviations shown below. On page 17, you'll find a glossary.
