Problem with TOPSAR-Split and Therman Noise Removal

Good afternoon,

I encountered a problem today when running a preprocessing in SNAP by means of a graph which I attach. The error is quite odd, because the graph is not very complex. As you can see, it consists in the following steps:

Read → Apply Orbit File → TopSAR-Split → Thermal Noise Removal → Calibration → Write.

Every step is set up with the following parameters:

Apply Orbit File → Sentinel Precise (Auto Download) and tick the box “Do not fail if…”

TopSAR-Split → You can either choose subswath 1, 2 or 3, however the processing doesn’t seem to work if you select a burst above 2. I mean, you can select subswath 1,2 or 3, but the processing must be limited to bursts 1-2, otherwise it does not work.

Thermal Noise Removal → Tick the box “Remove Thermal Noise”

Calibration > “Output sigma0 band”

The description of the error is quite cryptic, so I guess something occurs with the annotation of the data: org.esa.snap.core.gpf.OperatorException

I tried the following products from 2019 and all of them produced the same behaviour:


Many thanks in advance,
