[time-nuts] Excel logarithmic function (was Thermal impact on OCXO)

[Peter Vince]

Hello Lars,

Just out of curiosity I yesterday put just the first thirty days (like in
> the pdf mentioned below) and let Excel calculate the logarithmic function.

I'm not very good with Excel, but this curve-fitting function sounds very
useful.  Could you please tell me how it's done?

     Thank you,

          Peter
