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
