Gentlemen, one more lesson learned ( on my side, of course) . Usage of the Publications 229 or 249 of a non-current (outdated) epoch will noticeably affect the value of Hc. Not too much Z or Zn. And as the result the intercept will be quite different from what it was supposed to be. I used Publications of 1993 and check the data against 2001 edition. For the same LHA Aries Hc differs. Similar situation with LHAs of selected stars.
Just to be aware.
Thank you
