Hi,
I am trying to 3d print a tri Bahtinov mask for my cpc110,using this webpage :

https://satakagi.git...s/Bahtinov.html

For the apature diameter it is 280mm
For the inner diameter it is 95mm
But i have no idea what the following are and what to input:

StemWidth : SlitWidth = 1:1
Use 3rd order spectrum
Bartinov Factor:150
In W:5.99948
Out W:11.1125
Rounding

I appreciate if anyone can explain to me the meaning of the above and what numbers to input.

Thanks
