NOTE: As of Nov 2005 the following standards have been removed from the list of HET spectrophotometric standards.

Star Reason
BD+28 4211 has faint red companion
G158-100 too far south
Hiltner 102 no red coverage and poor wavelength resolution
Feige 15 no red coverage and poor wavelength resolution
Feige 25 no red coverage and poor wavelength resolution
HZ15 no red coverage and poor wavelength resolution
BD+08-2015 no red coverage and poor wavelength resolution
Feige 56 no red coverage and poor wavelength resolution
BD+25 3941 no red coverage and poor wavelength resolution
BD+40 4032 no red coverage and poor wavelength resolution
Feige 98 no red coverage and poor wavelength resolution
Feige 92 no red coverage and poor wavelength resolution
Further updates to the list above
Star Date Reason
BD+17 4708 20160921 ESO xshooter site reports binarity of this star and Ramirez et al. 2006 report this is probably no worse than a 3\% affect. Downgraded from P1 to P4
