ASH promoters

Hello!
I’m looking for a gene promoter, other than sra-6p, that expresses in ASH, but not ADL or ADF. Any suggestions or citations would be greatly appreciated. Thanks!

Osm-10?

Thanks, but I forgot to mention I was trying to avoid the phasmid neurons too.

Could you try a split-GFP approach, for example with nhr-79 and [i]osm-10[i]?
