Issue DM-6900: ci_hsc failure: insufficient PSF sources classified as stars
Since [ci_hsc#396|https://ci.lsst.codes/job/ci_hsc/396/], the regular ci_hsc build has been failing with: {code} [2016-07-05T23:59:53.929169Z] FATAL: At least 95% of sources used to build the PSF are classified as stars (49 > 50): FAIL [2016-07-05T23:59:53.929201Z] Traceback (most recent call last): [2016-07-05T23:59:53.929238Z] File "/home/build0/lsstsw/build/ci_hsc/bin/validate.py", line 3, in [2016-07-05T23:59:53.929249Z] main() [2016-07-05T23:59:53.929317Z] File "/home/build0/lsstsw/build/ci_hsc/python/lsst/ci/hsc/validate.py", line 53, in main [2016-07-05T23:59:53.929334Z] validator.run(dataId) [2016-07-05T23:59:53.929375Z] File "/home/build0/lsstsw/build/ci_hsc/python/lsst/ci/hsc/validate.py", line 163, in run [2016-07-05T23:59:53.929394Z] self.validateSources(dataId) [2016-07-05T23:59:53.929436Z] File "/home/build0/lsstsw/build/ci_hsc/python/lsst/ci/hsc/validate.py", line 201, in validateSources [2016-07-05T23:59:53.929451Z] 0.95*psfStars.sum() [2016-07-05T23:59:53.929510Z] File "/home/build0/lsstsw/build/ci_hsc/python/lsst/ci/hsc/validate.py", line 91, in assertGreater [2016-07-05T23:59:53.929547Z] self.assertTrue(description + " (%d > %d)" % (num1, num2), num1 > num2) [2016-07-05T23:59:53.929587Z] File "/home/build0/lsstsw/build/ci_hsc/python/lsst/ci/hsc/validate.py", line 82, in assertTrue [2016-07-05T23:59:53.929614Z] raise AssertionError("Failed test: %s" % description) [2016-07-05T23:59:53.929660Z] AssertionError: Failed test: At least 95% of sources used to build the PSF are classified as stars (49 > 50) {code} This error appears to be related to DM-5877: when I reverted to versions of pipe_tasks, meas_base, meas_algorithms, ip_diffim, meas_extensions_photometryKron and obs_subaru predating that ticket landing, the error vanishes. I note that [~nlust] reports that he does not see these failures on his (OS X) system, but I can reproduce them on Linux: we should investigate if that's just a coincidence, or if there is per-platform variation here.
