Radiometric & Geometric Correction Workflow

Greetings!

Thank you for the detailed steps for products processing. From the other hand, I have assumed some controversial with @lveci answer

That is, you missed the Thermal Noise Removal (TNR) step for SLC products, but from the @lveci answer I understand that this step is required.

Than, you recommend the TNR for GRD products, but @lveci told that TNR is already applied.
Sure, your answer partially explains the relevance of this step here

But how can I check the presence of Thermal noise in products I need?

Thank you
