The catalogue by Johannes Hevelius with the positions and magnitudes of 1564 entries was published by his wife Elisabeth Koopman in 1690 .
We provide a machine-readable version of the catalogue , and briefly discuss its accuracy on the basis of comparison with data from the modern Hipparcos Catalogue The full Table Hevelius ( Table 4 ) is available in electronic from only at the CDS via anonymous ftp to cdsarc.u-strasbg.fr ( 130.79.128.5 ) or via http : //cdsweb.u-strasbg.fr/cgi-bin/qcat ? J/A+A/ .
We compare our results with an earlier analysis by Rybka ( 1984 ) , finding good overall agreement .
The magnitudes given by Hevelius correlate well with modern values .
The accuracy of his position measurements is similar to that of Brahe , with \sigma = 2 ′ for longitudes and latitudes , but with more errors > 5 ′ than expected for a Gaussian distribution .
The position accuracy decreases slowly with magnitude .
The fraction of stars with position errors larger than a degree is 1.5 % , rather smaller than the fraction of 5 % in the star catalogue of Brahe .
