Folks, Both John Hart and I have conflicts with this week’s meeting, so I suggest that we cancel it. ``` Next meeting: October 30. ``` Jon ---

I think the meetings are very useful in keeping things moving. If we are below quorum for a live meeting, can we have a virtual meeting with a review of action items? We are eager to keep the project moving. ---

I will really be unavailable (at doctor’s office). I will ask Wei and Dingcheng to connect, so that they can give progress reports. That ought to work. ---

Is it possible to rename a topic? I’d like to remove “canceled” fon this topic. ---

Sorry for the late reply. Do we need to use Bluejeans for this meeting? Here is what I have been doing so far. Currently I was trying to establish the communication between the backend and frontend. And I wrote my proposed item into a [github wiki](https://github.com/DarwinSenior/LSST-Monitor-Frontend/wiki/Proposed-Communication-Scheme) And I made a small demo for that. However, there are few issues I ran into. For the first time I open the browser, I came across the violation of _origin domain policy_. However, if I refresh the page, there is no such problem again. I am not sure what happened. The server I set up is only for demo purposes, and might be noticeably lagging for multiple user. (Or even completely blocked). So, what I have done is to compute the average value for certain region. And the region is predetermined by the boundary I preset before. If you go to the page lsst.cs.illinois.edu, and type ```auto create_box box read_mouse box show_bounday ``` And hover the mouse on the displayed image, it will show the average pixel value. ---

Is the meeting id 107541143 or is it something else? ---

That should be correct. We are a little late getting started here at SLAC. Just connecting now. ---

Oct. 23, 2015. So now my script is able to combine all the raft scale FITS into a focal plane scale FITS. I’ve checked the header files. Both the original FITS and generated ones are of single extension. Prof. Jon @jjt can you tell us the source of the files? Things to do next: - Include more necessary information in the header of generated files. Add specification on what information we need for display and diagnosis. - Gap region between CCDs or Amplifiers which is not specified in the header? (Correct me if I’m wrong) - Test what parameters (especially memory size) are suitable for Firefly to display FITS of ~14GB. - Upload completed FITS files into shared directory (Dropbox). ---

Hi @gpdf, if i remember correctly you made a list of action items during last week’s meeting. Did these get posted somewhere? ---

> [@tony\_johnson](#): > > Hi @gpdf, if i remember correctly you made a list of action items during last week’s meeting. Did these get posted somewhere? Sorry, I’d misplaced it until now. Here are the notes: * * * @victor_ren still working on raft-scale mosaic - job is running now. Loading of raft-scale image tested by @xiuqin (10 seconds) and @victor_ren (13 second initial load, 1 second for refreshes after that). No progress on header keyword item. Discussion: what is the purpose of raft-scale files? Are they throwaways for use only by Firefly (whether created on-the-fly or in advance), or does the camera need an official format? Need a specification for what we want to be able to do with these files and what header information is needed in raft-level images. Some discussion of full focal plane images and the similar issues for them, but we decide to concentrate for now on raft-level images. - When displaying a raft-level image, we need to be able to get the CCD and amplifier IDs and the integer pixel coordinates within an amplifier. - Also need to be able to display CCD ID with integer pixel coords within the CCD - We need a spec for the nominal integer-pixel gaps in raft assembly ( **not** including the additional gaps for pre/post/over-scan, as post- and over-scan are in principle variable): @tony_johnson to drive a spec for what’s required and how to include this in the headers of the CCD-level 16-extension files. @jjt to tell us what the provenance of the raft-scale files already posted is, and what gaps were used. @victor_ren to post the inputs he used for raft assembly.
