Dear NCL community,

I have two questions regarding EOF analysis with NCL:

(1) For the function "eofunc_varimax", it states in the description:
"The result of varimax rotation upon standard EOFs are rotated EOFs
that are orthonormal. However, the temporal patterns derived by
projecting the rotated spatial patterns onto the data will not be
It is unclear to be on how obtain the corresponding PC time series to
the rotated EOF pattern?

(2) There seems to be no equivalent of the old function "eof2data" for
the new "eofunc" family of functions. Is the "eof2data" function
compatible with the output from the new function family?
