6 months ago I realized I had a concern that if there were two bundles with TeffStacker but one "normed" and one not, that they might run at the same time and have a conflict about the t_eff column. However, apparently we built MAF better than that and it does the right thing (runs them separately, rewrites the t_eff values, and comes up with the correct answers. Yay!
import rubin_sim.maf as maf
opsdb = '/Users/lynnej/opsim/baseline_v3.4_10yrs.db'
teff_stacker = maf.TeffStacker()
teff_stacker2 = maf.TeffStacker(normed=True)
bundle = maf.MetricBundle(maf.SumMetric(col='t_eff'), maf.UniSlicer(), '', stacker_list=[teff_stacker])
bundle2 = maf.MetricBundle(maf.MeanMetric(col='t_eff'), maf.UniSlicer(), '', stacker_list=[teff_stacker2])
g = maf.MetricBundleGroup({'teff': bundle, 'teff_normed': bundle2}, opsdb, verbose=True)
g.run_all()
bundle.metric_values, bundle2.metric_valuesproduces
(masked_array(data=[44791395.476532385],
mask=[False],
fill_value=-666.0),
masked_array(data=[0.6969573084883421],
mask=[False],
fill_value=-666.0))as expected.
values from the previous TeffMetric for the same run: All sky all bands 0.70 (normed) 44791395.48 (total).
I'll do the addition of the plotters we discussed as a separate PR.
