Maybe the FOV of both periscope is not perfectly set in cameras.dat? If so, which "AngularAngle" to set for "Cam_Periscope" and "Cam_Obs_Periscope" in cameras.dat?

Please, someone can help?

Vertical scale uses xx/16° graduations.

I ran the Naval Academy "Torpedoes" mission, and chose a target ship to use as a test: the Coastal Merchant that's pretty much dead ahead when the mission starts.

- ID book says this ship has a mast height of 20m.
- Weapons Officer reports the range as 800m.
- Measured range on the nav map confirms this range (near enough).

Using the attack scope reticle's vertical scale, I measured the mast height to be approx. 22/16° at 1.5x magnification, and approx. 90/16° at 6x magnification.

On the "Range with known target height" pull-out table, both of those measurements indicate a target range of around 800m for a mast height of 20m.

So, that all checks out fine.
