Enquiry about rotation pattern measurement

Dear All,

In radiation pattern measurement, are below combination correct ? There is a attachment for understanding what I mean.

Combination1 :antenna rotation 1 + horn placement 1 = Co-polar of XZ-plane (H-plane) ?

Combination2: antenna rotation 1+ horn placement 2 = Cross-polar of XZ-plane (H-plane) ?

Combination3: antenna rotation 2 + horn placement 1 = Cross-polar of YZ-plane (E-plane) ?

Combination4: antenna rotation 2 + horn placement 2 = Co -polar of YZ-plane (E-plane) ?

Thanks for your help,
