Licenses for Structure 101, Jeff follow up with Josh & Pat on Atlasssian Suite (Bamboo then Jira)
RH-7 waiting for NFS permissions
Verification Testing
When MPI tests are run in the framework, issues with the viewer and recent MPI updates are causing the tests to timeout (though they pass)
This is severely slowing down test turnaround
Julian and Darrell have been working with Akeem on this
It appears the problem is that the deamonizing of the viewer is causing problems shutting down the viewer
Test inventory spreadsheet
Just need a few last inputs: Masaya (Andy will ping him this week), Remy (no reply from email, and Andy can't seem to catch him in his office), Sanjay (on vacation), and Jim
Pipeline is not working as expected on OSX 10.11
casa --pipeline is not working, but casa --testpipe does
The working theory is that the pipeline is not installed internally with that build, but --testpipe option is installed in .casa/prelude and .casa/init.py, so that works
Akeem is working with Brian Kent on this
Imaging tests started running slow as of the 23rd, what checkin caused this.

VI/VB2 in tCLEAN it's working.
Pipeline
New standard ALMA imaging recipe, including new uv continuum subtraction heuristics and new threshold / niter estimation heuristics
CAS-8374 in progress (port casaqt to Qwt 6) - Lots of testing, fixed bugs in colorized plots, gridlines, external legends. Only remaining issue is latency between loading cache and drawing plot.
Investigating CAS-7817 (Bug while iterating over SPW) - plots differ when plotted as iteraxis (e.g. spw 19 plot when spw='17,19') vs. individually (e.g. spw='19'); looks like bug is in plotms antenna-averaging code
Kumar Golap
Making it possible for ComponentList to do simulation. Need to open Jira ticket.

Viewer
CAS-8458: Viewer Spectral profile tool line display should include line temperature
CAS-8512: Viewer misaligns optical and radio velocity
CARTA: Profile work, fix of some memory leaks, unsuccessful efforts at getting scripted client tests to pass.

CAS-8497,,exportuvfits possibly incorrectly writing antenna coordinates: Pinged Jeff about this since this code remains unreviewed after two weeks.
(CAS-8569) improve performance of reading columns in Main table in MSMetaData: Resolved. Decreased listobs run time on Steve Myers' 0.5 TB data set by 15%. Since I began work on optimizing MSMetaData 's listobs specific methods, I've decreased the listobs run time from 11 minutes to 48 seconds on this data set on my eight core linux box. Thanks to Julian for all the code reviews.
(CAS-6906) avgchan in exportuvfits not changing number of channels in output: WIP. Considering using MSTransformer for preprocessing these types of transformations prior to writing uvfits since the uvfits specific code to this reportedly is buggy and is certainly convoluted.
(CAS-8565) integration interval fluke in listobs: Resolved. Not a bug. Suggested reporter query whomever is responsible for applications upstream of listobs as to why the MS intervals for this data set are peculiar.
(CAS-8570) ia.moments doesn't close output image correctly. RTT. Fixed. Similar issue for ia.imagecalc() also resolved.
Attended CIS security briefing. Asked Pat afterwards details on secure ways to destroy hard drives that can no longer be attached to computer so cannot be wiped with software. Learned that one of the methods used in GB is to use them as target practice.
(CAS-8525) robust statistics "fit-half" not working: RTT. Fixed.
(CAS-8529) Modify MSMetaData::_getExposureTimes() to improve performance. Resolved. Implemented.
(CAS-8500) imhead will crash on fully masked images. RTT. Fixed.
(CAS-8441) MSMetaData::getSubScanProps() is returning exposure times for mean intervals. Resolved. Fixed.
Attended Joanna Corby's thesis talk. Began thinking of design for implementing her automated spectral line identification and fitting tool in CASA. Will set up meeting with her and Remijan when she returns to CV.
(CAS-7202) boxit crashes when imagename ends with '/' and error isn't very obvious. RTT. Implemented more general solution to escaping special characters in the LEL. mask expression.
(CAS-8528) improve listobs performance by adding wantreturn param to ms.summary(): Resolved. Implemented.

CASA RPMs building on RHEL7 (waiting on NFS permission issue)
Got Carta to compile on RH6, but the runtime doesn't work right: Won't render the image and segfaults at exit.
Tested Bitbucket Subgit plugin with Asap, which seemed to work alright. Tested syncing SVN BranchGit master, seemed to get only a partial history. Need to test again.

fixed watchdog process hanging around for 2 minutes after casa end
fixed namespace pollution of plotms/casaqt headers causing conflicts with Qt::QVector and casa::QVector, please don't use 'using namespace' in headers
