Hello all, I seem to remember that when I first read about the Bernhardt precision dial, mention was made of the effect of different levels of sunlight and haziness on the edge of the shadow of the thick curved gnomon.
Apparently, the gnomon thickness across its height was corrected for the typical variation over the seasons for mid-west Europe. I see no mention of this on the web site, however.

Isn't it odd that so little has been written, prior to now, about the effects of weak sunshine on gnomon design? -- No virus found in this outgoing message. Checked by AVG Free Edition.
