Baseline Perpendicular Value (Bperp)

Hi

I want to asking about baseline perpendicular in InSAR Stack Overview menu.

My question, is there specific value to produce best result for InSAR or DInSAR method?
An example, baseline perpendicular value could not more than +30 or -30.

and, is there maximum temporal (between master and slave imagery) to produce good baseline perpendicular value?

Thank you before.

there are quite many studies investigating this, however under different aspects, so an absolute value cannot be given for any application:
