Align channel_stats transform when more than one file is used in ingest #241
Description
Description
The channel_stats transform when used with ioda_obs_space seems to not function correctly if more than one file is specified in the input dataset. In this case metaData::channelNumber doesn't align with the [group]Mean::[variable].
In the specific instance I've been working with I need to make 2 plots in one image. In the first plot each of the 4 files is loaded into a unique dataset (cycleOne, cycleTwo, etc), and then the channel_stats transform is applied. In the second plot 4 files are loaded into a dataset named oneDay. When I apply channel_stats to that dataset the mean and std are correctly dimensioned to Channels but oneDay::metaData::channelNumber is dimensioned to Channels,Locations and doesn't match the mean and std variables. I'm able to generate the 2nd plot by using x=cycleOne::metaData::channelNumber, y=oneDay::ObsValueMinusHofxBcMean::brightnessTemperature, which seems a bit hokey but it works.
Since I have a work-around I'm not treating this as a high priority item and will investigate it as able, but I wanted to document the issue so I don't forget it.
