[WIP] Periscope accurate Field of View (US, IJN, French, British)

While I was writing my previous post, you found the French periscopes specs. Good

Leave it to the French to come up with such an odd combination.
High Power is 6x magnification with a 6 degree FoV
Low Power is 1.1x magnification with a 40 degree FoV

The point is they don't add up with each other like the American periscope.
High Power is 6x magnification with an 8 degree FoV
Low Power is 1.5 magnification with a 32 degree FoV

You see, the American figures are of a multiple of 4 which help in keeping a target height or length in a direct connection, whether you use either the high or low power magnification. For the French to use the Telemeter division marks, there was probably a set just for the low power magnification and a separate set for high power.

And, since the French have such a different Low Power FoV of 40 degrees (the German periscopes were 32 degrees), my Omnimeter for finding range when counting the Telemeter divisions up to a known height will be useless.


=========

Keltos, I noticed something else about the "AngularAngle=" on the Silent 3ditor image you posted. That figure should read 62.4814 not 62,4814. Put a decimal point after 62.
