17th century photometric data in the form of telescopic measurements of the apparent diameters of stars BY Johannes Hevelius.
GRANEY C.M.
Abstract (from CDS):
The book Mercurius in Sole Visus Gedani published in 1662 by Johannes Hevelius contains a table of magnitudes and apparent telescopic diameters of nineteen stars. The data fit to a simple model, suggesting that Hevelius produced what is essentially a table of surprisingly precise photometric data.
