Thanks for the link. It is the one I've been using to get the raw images. It has a lot of data there that is useful but the table in the link is dated and does not include the images released yesterday. A new or updated table would give me all the data I need.
In the meantime I must apologize for the reply #24 pic. It seems to be really of two filters only; an infrared and 2 natural dark filters. There is no indication of where the "before" images are therefore from the data released so far it does not seem possible to tell with certitude what those objects are except that there are strong indications from other pics that they are of the substrate.
