What are the specifications for hydrocracking tail oil?

As the title indicates, what are the specifications for hydrocracking tail oil? How to determine the conversion rate from metrics? Please ask the fellow sailors to answer.
At present, only flash point and viscosity are controlled; ultimately, it still depends on market demands
In addition to the normal boiling range, parameters such as acid value, moisture, residue, sulfur and nitrogen content, and BMCI value are usually also considered
Thank you. In response, what are your typical metric parameters? Please let me know. Thank you.
In fact, as an intermediate product, the specifications for hydrogenated tail oil are mostly determined by the requirements of downstream facilities. The sulfur and nitrogen contents indicate the effectiveness of desulfurization and denitrification processes. Of course, if cracking takes place in this unit, the requirements for denitrification become very strict; for example, regarding the nitrogen content in the refined oil
