The result of Rayleigh Correction

Hi, Marco!
There are only two type results of Rayleigh Correction when I checked “Compute Rayleigh optical thickness bands” and “Compute bottom of Rayleigh reflectance bands”.
My question is taur_.img and rBRR_.img correspond to “rayleigh optical thickness” and “bottom of Rayleigh reflectance bands” respectively?
And how can I compute Ozone optical thickness in SNAP?
Thank you.
