Thanks Robin for the interesting link. Is there also an option to search for reddening factor for any particular star?Robin Leadbeater wrote:Hi James,
SIMBAD is not a very reliable guide to spectral type. A better source is Brian Skiff's huge database of references

There you will see the M2 reference from 1956 and a more up to date reference M6III
Where does this dialogue box come from? I am not sure I understand the connection between spectral type and BeSS and how it might be used
Cheers
Robin
