Comment 2 for bug 1801519

> What is datahugin_rt.pp3?
I should be data/hugin_rt.pp3. In this I reset all crop because the optical model assume that the optical center and the image center are identical.

>2. Use uncompressed 16-bit TIFF files as intermediate files,
Hugins default for the remapped files is LZW compressed TIFF files. So I used the same format also for the developed raw files.

> Changing the above command as needed, the final command should look as follows:
According to https://rawpedia.rawtherapee.com/Command-Line_Options -b16 is the default:
     -b<8|16>

        Specify bit depth per channel (16 by default).
        Only applies to TIFF and PNG output, JPEG is always 8.

    -t[z]

        Specify output to be TIFF (16-bit if -b8 is not set).

Is the documentation wrong? Or is -b16 really the default?
