Greetings,
I have seen for a few stars in VSX that have an A/H= value that seems to range from -1.0 to +0.2 in the remarks. I have searched and searched on the GCVS web pages, the literature and I have not found anything that describes what A/H is.
Of course, VSX has copied the remark.
Anyone got an idea what A and hence H constants are?
Thanks, (DEY)
