Couldn't this be automated for those with the K3EXREF?
Since the K3EXREF is applying a "fudge factor" (technical term) based on the
instantaneous error of the 49 MHz TXCO, one could "simply" read the
correction and the front panel temp over a thermal "run". The data could
then be massaged (another techinal term) internally, to come up with the
tabular data needed. Yes?
