AGMA 926 - Whats This Symbol for Case Depth?

[SwaggingIt]

I'm looking into case depth calculations for 9310 gears and and AGMA 926 has this reference for minimum case depth but I do not know what the C with a vertical line through it means. Theres no key for symbols in this standard.
Thanks for the help!

This graph is pretty much the same as in AGMA 2001 which doesnt have this symbol. So I used the AGMA 2001 method for case depth, but Id love to know what that symbol means if anyone knows. Thanks.

As terrible as the kerning is for some of the axis labels, it may be a problem with a glyph substitution. I'm going out on a limb and guess this is from a PDF formatted file and it's possible that someone either embedded the wrong font or used a font that has an identical name to a later font and the glyph from the later font isn't what was intended.

A search indicated that this character may be used in musical notation as a time signature.

"In music, a C with a line through it is most often called “cut time” or “split time”, or alla breve."

It can also be the cent symbol for currency.

From some online locations I see that copying that symbol and asking Google about it says it is the cent symbol.

It's multiplication.

the formula is suppost to be effective case depth = .120 x diametral pitch
how ever the symbol I believe is a typo , multiplication symbols are x , * ,
