**Agenda:**

- Discuss Image display commands:  
I have updated the image display use cases (pp. 8-9 of the [Google Doc](https://docs.google.com/document/d/1MM_FzbVK_gGoLQtS63z_SkQ67gx2iP5wa6opu3tLeBM/edit#)). There are some subtleties that I’d like to discuss.

- Status of last week’s action items:

> Test the code at SLAC: \*\*Action:\*\* @weiren2: Put up to date code on GitHub. \*\*Action:\*\* @marshall and @tony\_johnson: Put together an environment that is similar to what we will have at BNL. For example: verify the FITS image merging time.  
> \*\*Action:\*\* @dyue2: Implement the client-side `display_latest` command, with a button for `pause/resume`. \*\*Action:\*\* CCS people (\*e.g.\*, Homer?) Provide an image access tool.  
> Prepare for raft and focal plane scale images: \*\*Action:\*\* @marshall: Make a proposal for the header format. \*\*Action:\*\* @gpdf: Coordinate the header discussion at the project level. People to include in the discussion (please edit as appropriate): &nbsp;&nbsp;&nbsp;Stuart, Tony, Steve Ritz, Paul O, Seth, Homer, Peter D, &nbsp;&nbsp;&nbsp;Chris S, Andy C, John P. (others?)
> 
> **Notes:**  
> **Action:** @tony_johnson For next week SLAC should create a service “Is a new image available?”
> 
> Stuart is ready to begin testing. He should tell us about problems/issues.
> 
> **Action:** @weiren2 Document the scripts, to help Stuart get going.  
> **Action:** @weiren2 Document the utility scripts that make displayable FITS files.  
> **Action:** @marshall Talk to Max about the CCD WCS headers.
> 
> @tony_johnson says that CCD WCS keywords should not be a project-level issue now. @gpdf is worried about consistency between test stand and simulated images. He agrees that it’s not yet a DM issue. We should proceed to reach our  
> short-term goals.
> 
> Add Chris Walter to the header discussion.
> 
> There will be a camera meeting in June 13-14. Agenda is in Confluence.  
> Hackathon? @dyue2 and @weiren2 might attend.
> 
> **Action:** @jjt Fix “daemon” nomenclature. **Done.**
