THE ANALYSIS OF STAR CATALOGS .2. AN INTERCOMPARISON AMONG THE GC, THE N30, AND THE FK5 (B1950.0 FK4)/

We use the general method of compiled data set analysis developed in o ur first paper and extend our analysis of fundamental star catalogs to include the two American ones. The problems found in the FK3/FK4/FK5 sequence are not present in either the GC or the N30. This lends suppo rt to the hypothesis advanced in our previous paper that the FK3. and to a lesser extent the FK4 declination system, are distorted by high a ngular frequency systematics. On the other hand, both the GC and N30 e quatorial coordinate and proper motion distributions nicely follow the predictions of mathematical statistics. As with the FK3/FK4/FK5 analy sis, the new results are as seen by the FK5 (on the FK4/B1950.0 system ).
