ATM RAts! Schmitd corrector worksheet problems of Dave Rowe




I got a copy of the Schmidt Corector spreadsheet from somebody that was
backdated to Excel version 4.  I have a problem with the spreadsheet on
cells B33 and B34.  I have a number in there and it sort of looks like there
should be a formula in there of some kind or another.  I'd like to hear from
somebody privately that has the original calculator or the guy that did the
conversion for me.
I'm in the last stages of getting ready to make a corrector for my 6"
Schmidt Gregorian and I don't believe that the calculator is working right
as the vacuum needed to do the corrector doesn't change with changes in some
of the parameters.
The program won't change the vacuum needed for the change of the number of
surfaces from 2 to 1 (something that it should do as the curve needed is
less for 2 sides than 1!) and other values are also not doing anything.
I went and moved the A and B values from B20 and B21 down to those positions
and the numbers do change but I don't know if this is the right thing to do.
Somebody help?  I don't believe that I'm the first person that has actually
used the spreadsheet to calculate a corrector plate vacuum.
