f19_g17_rx1 grid was removed from ccs_config, which grid should replace it for DROF testing?

[ekluzek]

The f19_g17_rx1 grid was removed in ccs_config by @alperaltuntas in March 2025. There's a test for it in aux_cdeps that we need to know what to replace it with.

The grids still available are ones with the POP ocean mask which seems like we shouldn't really use.

MOM does a bunch of tests at TL319_t232, which uses JRA025 grid for DROF, so it seems like it should be that one. But, asking @alperaltuntas and @mnlevy1981 for confirmation.
