I happened to be awake early this morning and Corona Borealis was well placed so I thought I would try and get an upper limit to the brightness of T CrB using bins. All was successful except I couldn’t load my entry into the database. I have attached the error which I can’t understand. The faintest star I could see on chart 025.04 was star P at magnitude 8.4 so T must have been fainter than this. My entry was
Hi Duncan,
As Gary has alluded to, you need the fainter symbol in front of both the light estimate and the magnitude, so [P and [8.4.
With normal magnitude estimates an “=” is assumed, so just 8.4 means equals 8.4.
This is all to do with the way the database verifies the data, and can recalculate magnitudes when a sequence is updated.
Best wishes,
