      Description

      DM-9136 is editing LDM-151 to reflect requirements from the beam projector. These need to be added to DMSR. See LCR-581.

            I have added this requirement to the EA model as DMS-REQ-0351. Patrick Ingraham would you be able to do a quick review of the DM version? It can also be found in the new draft non-preferred version of LSE-61 on Docushare at https://docushare.lsstcorp.org/docushare/dsweb/Get/Version-42765/LSE-61-20170216-with-history.docx

            My only request is that there be a graphical representation of what is happening. Showing a (rough) Gaussian ray trace through the system that shows more-or-less where the CBP is hitting the primary mirror and approximately what the user should expect on the detector would be useful so users can better picture what the setup looks (or looked) like.

            If we don't make the tool people will be forever looking for napkins to draw on. In fact, I'd be surprised if you can get the transformations right without a tool to guide you..

            Could we maybe add in the discussion that a graphical representation of the solution is expected?

            Following some discussion on email, DM does not feel that they can sign up to a visualization tool to be delivered for daily use of the operations team. They will be doing some visualization but there is no guarantee it will meet stringent operations requirements. Patrick Ingraham I take it that I can go forward with my proposed wording and visualization can move to a separate discussion, possibly involving telescope and site.

            Yes.

            T&S will do any required visualization for operations using the output of the (non-visualized) DM coordinate transformation tool

            Patrick Ingraham Thank you. I will retain the existing wording.
