Here is a list of regions where we suspect there is erroneous data in the star catalogues.

Region Bounds (RA/Dec - J2000) Possible causes Appears in catalogue #'s Status (see note 1)
16h33m20.2s / 26°26'55" Antares spikes on original survey images? 7 Identified
5h13m54.5s / -7°50'16.9" Suspected artifacts near Rigel 7 Identified
HP104297 Spikes scanned as red stars  ? Identified
HP104139 Spikes scanned as red stars  ? Identified
HP103976 Spikes scanned as red stars  ? Identified
HP103920 Spikes scanned as red stars  ? Identified
HP103825 Spikes scanned as red stars  ? Identified
HP103976 Spikes scanned as red stars  ? Identified
HP105515 Spikes scanned as red stars  ? Identified
21h32m17.8s / +48°28'10.3" This mag9.85 star does not exist  ? Identified
5h38m44.4s / -2°40'19" The mag8.2star does not exist  ?
Virgo Constellation Inconsistency : SkyAndTelescope.com 's chart: http://imagebin.org/100486 and Stellarium's: http://imagebin.org/100487 . +1 to S&T's from my observations.  ?
4h 14m 9.6s/-7deg39' 45.1s (near HP19849). A straight line of about 20 stars around mag 13 to 15 plus other "unnatural" lines of stars in same region seen when fov ~0.5 deg or less. 6 and 7 Identified
0h 14m 14s / -7deg 37m 2s (near HP1158) panel of artifacts. Forming squarish patterns? FOV .3 deg 6 and 7 Identified
HP54904 Fainter clones along 2 sides. FOV<=2 4 (?>=4) Identified
HP52343 Fainter clones along 2 sides. FOV<=2 4 (?>=4) Identified
HP51966 Fainter clones along 2 sides. FOV<=2 4 (?>=4) Identified
HP49742 Fainter clones along 2 sides. FOV<=2 4 (?>=4) Identified
HP21218 Too many fainter clones along 2 sides. FOV<=2  ? Identified
HP11954 Fainter clones along 4 sides. FOV<=2.5  ? Identified

Notes

1: Status values

Please use these statuses:

  • Identified - a rough description of the problem has been done - i.e. the RA/Dec added to the table above.
  • In Progress - someone is currently trying to list all the stars which are affected.
  • Detailed - all bad stars have been logged.
  • Fixed - the catalogue files have been fixed in the development repo.
  • Released - the fix should have been released and available for download.
