If I interpret your response correctly, I understand the table in such a way that by using

StdLatticeParm(HEStd\_error, 65536, HEStd\_192\_classic, 1230),

I achieve a security level of 192 bits with a ring dimension of 65k and a maximum log(Q) value of 1230. If this is the case, how do I specifically reach this maxLog(Q)?
