You know know where the plate boundaries on the DSS are? That is : the system joins the plates? I thought the DSS was a one file thing like the Plan(c)k. If skyview ( not related to sky net ) has knowledge of the exact limit between plates, I sure could due that information, particularly of it can be served as a vector file. I have to generate or guesstimate where the plate boundaries are in order to create a mask to flatten the field manually. It provides continuity which I need to refine the ism signal . In photoshop the information I am referring to is called a vector mask . It’s post script ( I think )

The blog post says that sky view ( not related to sky net ) joins the plates and it does a job of this . Every time I encounter a poorly matched boundary, almost always , nothing less than perfection is desired here, I find my self laboring to emphases the boundary.

The vector mask is used to burn and dodge the plate into flatness . Getting the boundary masked is repetitive task, that the machine is already aware,numerically. it should not be to difficult to generate a file , a PostScript file that relays boundary information to the user . And I may be the only user . That’s not so good. On the other hand. The length of time needed to rectify the field flatness at plate boundary for clean joints could be cut in half or more if the boundaries are machine generated. It implies that the whole survey could be fixed. More easily than I thought . IAC
