Hello,
I want to find what power are in every 10 degrees of TABO schema of some lens.
I am using next formula to find powers in meridians: Fsph + Fcyl*sin^2(alpha).
For my purpose there is no need for more precision calculation. But, angle is problem. With this formula I get power in some meridian on some angle away from axis but no with respect of TABO shema. If some lens have power +0,42 Dsph = -0,84 Dcyl ax 127,05, what is power on 0, 10, 20... degrees but with respect of TABO schema. I am currently reading some article and I want to check numbers on pictures. Here is link:

Thanks in advance
