Adjustments run in simultaneous or phased-multi modes are not affected.
DynAdjust version info
Version: 1.2.7, Release (64-bit)
Build: Mar 29 2023, 10:01:09 (MSVC++ 1935)
Steps to reproduce
To reproduce:
Run a network adjustment in phased-staged mode
Reproduce the adjustment results with adjust.exe using the following commands:
Thanks for your recent efforts to review this issue, @rogerfraser.
To summarise our email exchange, the above behaviour is the result of the combined use of --report-results and --create-stage-files which re-creates the empty stage files containing the a-posteriori measurement/station variances matrices (initialised as zero) and then reports the zero results from the newly initialised and unpopulated stage files.
Therefore, the action required to prevent the above result is to modify adjust such that it will:
refuse to proceed when both --report-results and --create-stage-files options are provided; and
Many thanks @nicgowans for confirming the behaviour of the issue, and for suggesting a fix to prevent adjust from inadvertently producing incorrect results. A fix to trap the combined use of --report-results and --create-stage-files has been implemented and will appear in the 1.2.8 release.
Description
Zero variance matrix components are reported by adjust.exe in
--report-results
mode when a phased-staged adjustment is run. The effects are seen in:Adjustments run in simultaneous or phased-multi modes are not affected.
