Final fix to test_simobserve.py for new parameter comp_nchan testing for CAS-12572
Add reference to new, channelized interferometric data to serve as reference values for testComp_intNchan in test_simobserve.py for CAS-12572
Enable piecewise comparison of image frequency coordinates in _get_imstats method of test_simobserve.py for CAS-12572
Remove self.comp_nchan reference from testNZ_sdAtm_dnu and testNZ_sdMan_dnu; add parameter settings to testBad_compwidth and testBad_comp_nchan
Update test testComp_intNchan in test_simobserve.py for CAS-12572
Create new simobserve tests testComp_intNchan and testBad_comp_nchan; update all the tests that call compwidth to also call comp_nchan; add default test value of 1 (parameter default) for comp_nchan for both test classes that use components (simobserve_comp and simobserve_skycomp) for CAS-12572
Reformat some long lines to PEP8 compliance in task_simobserve.py for CAS-12572
Update task XML to enable new simobserve subparameter 'comp_nchan' for CAS-12572
update component-only msg output in task_simobserve.py for CAS-12572
Add new parameter 'comp_nchan' to task_simobserve.py for CAS-12572
Merge pull request #1064 in CASA/casa from bugfix/CAS-12576 to master
* commit '467a04421c5094d32034b808d383cb2cd8071471': CAS-12576: In SingleDishSkyCal::calcWtScale, moved CTInterface object into the iAnt loop, as this seems to prevent ct_ from remaining open in the table cache.
Merge pull request #1060 in CASA/casa from bugfix/CAS-11552 to master
* commit '35bf661f252ff7223ae6ec3220530f5041cadabe': CAS-11552: Repairs for defects discovered in testing: corrected frequency label for MBDelays, fixes to shift theorem application for heterogeneous spws, updates to associated c++ unit test (including some minor updates to how test data is generated in SimpleSimVi2).
(CAS-11552) Improve multi-band (combine='spw') delay solution support: (1) Handle variable nchan, chan-width, total bandwidth, and arbitrary frequency registration over spws (including use of data weights and removed normalization by channel amplitudes), and (2) Do it correctly for the LSB case (combined spws must all be of the same sideband, for now). Also improvements to tKJones_GT.cc.
