Orfeo Mosaic not working as expected

Context

I am trying to mosaic two small temperature rasters that overlap a third larger temperature raster with the aim of creating a seamless temperature raster.

Configuration setup

My system: Windows10
Python version: 3.9

Description of my issue

*I want to mosaic three temperature rasters that overlay

I have set the parameters to use -comp.feather large and -no_data -9999. The output has clear seamlines. How do I get rid of the seamlines?

Hi @Caley-97.03_08,

Thanks for feedbacks.

Please, could you shared the inputs products if possible and the full command line do you use?
Otherwise, could you shared the dynamic range of the inputs?

Thanks in advance.
Best regards.
