Educate me please

people are mentioning filaproms. I've googled but can't get a descent description of them. Also if this is one type of prom are there others?

An explanation or directions to an online resource would be most welcomed. Pictures would be great.

Cheers

Steve

A filaprom is where you have a filament on the disc which runs into a prom on thr limb. Filaments are proms which you are viewing from above. There are lots of descriptive names for proms;arches, hedgerows, loops, trees etc. These names just describe their shape.
