I downloaded your OTC, located here http://www.subsim.com/radioroom/down...o=file&id=3333 You said it helps with the stadimeter ranging. Which file does that?

Specifically, the stadimeter is helped with it's accuracy when the targets ship Height: measurement is at least close to what it should be. Many of the measurements are off....some way off. By correcting the "height" measurements to the actual range distance the game states the target is really positioned (I make test missions that have all targets sitting at a specific distance from the sub, then calculate what the height measurement should be to provide the same range distance), I'm able to get a much more accurate stadimeter measurement. This takes the blame for missed targets away from the subs "equipment", and places it where it should be.....on the Captain's expertise as the "Approach Officer" leading the firing party.

It's my opinion, the Navy made every effort for the sub to preform as it should, with the best intelligence of the day. As an example, the Navy actually preformed measurements to help "Bore Sight" each torpedo tube for accuracy when in dry dock! The boat was expected to fire straight and true......it's the human factor that's brought into question when talking about accuracy of a firing solution.

Here's an image of the Nagara Maru having a "Height: 66.3 ft" tall at the funnel. The picture in the Recognition Manual will have the "Stadimeter Point of Reference" marked in red..... that's where you put the waterline image. With accurate periscope Telemeter Division lens marks, and the view properly "scaled", you can count the divisions and use the OTC Range Omnimeter to find accurate range (as in the picture). It's just another way of getting the range to target when needed.




I mentioned earlier in this thread about the original stock game's Hiryu having a mast height of only 20 meters (65 ft). In the 4th patch (v1.4) the developers changed the Hiryu mast height to 31 meters (102 ft) as seen below:





Notice the range in the PK gleaned from the stadimeter as 2326 meters (2543 yrds) using the mast height of 31 meters (102 ft) tall. The ship is actually placed at 1828 meters distance (2000 yards true distance)....that's about a 500 meter (547 yrds) difference in an accurate found range.

The accurate mast height should be near 37 meters (127 ft) tall to give an accurate range measurement. As in the following picture, the stadimeter taken reading has the target sitting at 919 meters (roughly 1000 yrd) range.....that's just where I placed it in this particular test mission. The following OTC image shows a Japanese flag added to the Hiryu's mast.....this national flag top is where you place the stadimeter's waterline image, regardless where the mast top may be seen (the flag is much easier to "see" than a mast top.....you just assume the top of the flag is attached to "something"....like a mast top).






Not all mods pay much attention to the manual targeting side of things. For instance, TMO 2.5 has the Hiryu mast height set at the original 20 meter height.....an oversight I'm sure, but don't expect to get a good range reading with the stadimeter using TMO on the Jap Hiryu.

To answer your direct question, the "MastHeight=" figure used for the Stadimeter and in the Recognition Manual is found in the Data/Sea/ShipName.cfg file.

Plus some of his other goodies

Thank you
You're very welcome Carroll.....thank you right back!!
