[Dachs-support] SODA error with 3d data

Hello,

I am having some trouble using the SODA resources for 3d data, 
specifically with the velocity axis. I just made an example for cutouts 
with "//soda#fits_genDesc" and <FEED 
source="//soda#fits_standardDLFuncs"/> that fails when setting the 
velocity min and max (real values, not pixels) and also fails to scale 
the image. The result when I click "retrieve data" is just the FITS 
header, with the CRPIX3 keyword changed. On the other hand, if I use the 
inverse order, max and then min, for the velocity I can retrieve the 
cube correctly (although CRPIX3 still changes). The cube I'm using has 
RA--SIN, DEC--SIN and VRAD; the spatial coordinates work correctly.

Is this a normal issue and is it possible to fix? Any help is 
appreciated.

Thanks and best regards,

Ixaka Labadie
