Re: [ATM] Cass Cal has error-(was Cass sep)


It seems the correction notice given out by Will-Bell
for line 2450 on pp345 in Texerau for the Basic
version of the Cass calculatorhas not been
incorporated into the Win/java version making the
result for secondary size,for fiels U,different from
what it should be.Line 2450 should read
D2=F/57.29578*U .This isn't that crtical as long as
you stick to stock secondary sizes.This also affects
the slope error value for the secondary and the
epsilon value.

THe rest of the parameters are valid,so it is still a
useful tool.The use of only two decimal places in the
Java version,versus the three in the Basic version
does affect some of the values,as in a 1/10 inch
difference in spacing tolerance.Picky perhaps but for
fast primaries might make a difference to some.
