Stack geocode: parameter confusion

[riyasmjgeo]

I have prepared a sentinel stack and I wanted to geocode the products.
The program geocodeIsce.py requires REFERENCE and SECONDARY directories. I have doubts about these parameters. Should I give the reference according to the reference used in the stack or should I assign the reference of the pair I wanted to geocode?

An example case:
I made a stack with 20200101 as the reference for the stack. The stack contains many pairs and 20200202_20200208 is a pair that I wanted to geocode. In this case, which is the REFERENCE to be supplied to geocodeIsce.py? Is it 20200101 or 20200202?

For the stack processing, the reference date for the stack should be used for the geocoding. That is the date that has the geometry data.
