Export sigma0 values as CSV for multiple images

Hi,

I have done preprocessing of all about 60 sentinel 1 GRD images and I would like to export the sigma0 in DB as csv files for all the 60 images at once.

Is there any easy way to export the sigma0 into a csv file?

Thanks

CSV is quite unhandy for raster data, I coul imagine that this produces massively large files. Is there no other way to proceed? Most raster formats can be dieectly accessed with scripting languages.

If not: Running an export graph in batch mode could work.
