n. slang for bona fide purchaser, consequently somebody who bought anything (example. a bond, a promissory note, or jewelry) with no reason enough to be dubious it was taken, belonged to someone else, or had been susceptible to another party's claim. The BFP should have compensated the full and fair price and possess gotten that when you look at the normal span of business, otherwise she or he might have some doubts ("wanta purchase a watch, inexpensive?" from a character on a street part).
The anomaly is then the angle BFP which the radius vector makes with the major axis.
