Thanks again. I didn't realise that there were 2 pages to the pdf table. However it still goes to sol 30 only and there is no reference to the sol 12942 rotational position so I don't see a way yet to identify the substrate for that image. It seems as if the numbering system for the rotational position that links the substrate is quite obscure and perhaps unnecessarily so. Why could'nt they provide a number in the label that identifies the substrate? Why go to the necessity to have special tables to do this when they should be able to embed that information in the label for the image? Or have they done this already? Anyone knows how the label is decoded? That info has been published for the SS images. Why not the OMs?

Thanks again for the heads up on the "before" image for the 12942 rotational position. I suspect the substrate for those images was probably the textured substrate. If so, it's difficult to see how that substrate could be used to identify ambiguous and possibly non-mineral particles.
