Any objects with proper motions higher than 3276.7 mas/yr that were taken from the UCAC catalog had their proper motions put to 3276.7, 3276.7. For the IGSL this occured for the following sources where their proper motons should have been:

Some RA or Dec values are out of range:
For the GSC23 and SDSS objects when there is a proper motion from the PPMXL it was applied to bring the positions form the epoch of observation to 2000. These new positions were not normalised to be within normal RA/Dec ranges and 34 have remained outside the nominal range. They should be normalised.

Errors in the Classification:
The classifications have two problems. The 167055567 SDSS objects have their classification inverted, that is stars are classed as 1 and non-stars as 0 or -1. The 197921 GEPC non-stars are classified as 3 instead of 1.

Some objects do not have unrealistic magnitudes or nonsensical errors for a number of reasons:
All objects from the HIP, SPSS, SKY2000, LQRF and GEPC catalogs were included even if the magnitude information was not complete. In the case of OGLE/TYCHO2 objects the relations 10, 13, 16 and 17 are only valid to B-V or BT-VT of 2.5 so those objects were not assigned $R_F$ & $B_J$ magnitudes. Finally some objects just had unrealistic magnitudes so we also assigned NaN for that magnitude. The TYCHO2 catalog some times did not include the blue or red magnitudes and they were taken from HIPPARCOS, unfortunately in these cases the errors were not updated and they have remained zero as published in TYCHO2.
