Here is also a table of corrections for
local apparent noon latitude calculations in SH5 world which I have created during my extensive testing.

Note that this applies to TWoS only. I still have to learn and test longitude calculations, lat/long determination using stars ect. In general my conclusion is that in SH5 world the "sky" is accurate and follow real world rules but certain corrections have to be applied for highly accurate results... Happy navigating.
