[vsnet-chat 6634] (fwd) re NSV 16694 V-Ic corrigendum



(fwd) re NSV 16694 V-Ic corrigendum

   The following message is from John Greaves:

Can't add up.  V-Ic for NSV 16694 is +1.0 unreddened, not +0.1, and not too 
blue for the B-V, but in red excess, probably due to the associated nebulosity.

Similarly, I think I'm a bit befuddled about Ic being in excess if the objects 
are sometimes appearing too blue.  Can't be right.  I know I got the values 
right for the two mentioned (I've others results to check against for 
MisV1147), so I'll have to go back to what was my original thought, and that 
the Herbig Ae/Be stars are burning a bit bluer than their main sequence 
analogues for any particular spectrum, in tandem with also burning a bit 
brighter than them.

The inverseness of the magnitude scale gets me muddled sometimes.  Sorry.

Cheers

John
