Does somebody (Bill or others) can explain how Guide 9.0 estimate
the magnitude of the asteroid ?



I would like to know which parameters and equation Guide use for it
estimation. I made precise estimation of asteroides via a ccd images and I
would like to compare it to the theoritical estimation.



Does just the distance to sun-asteroid and asteroid earth are use ? Does
Guide use and aldebo factor ?



Is there any useful reference that I can consult ?



Thank you
