what does `inflation factor: 0.0` do? #201

I saw lots of inflation factor: 0.0 in yaml files under rrfs-test/validated_yamls/templates/obtype_config/

Here is an example: https://github.com/NOAA-EMC/RDASApp/blob/4224998744ee5fabe1411d3f68b146e9e6b7548a/rrfs-test/validated_yamls/templates/obtype_config/aircar_airTemperature_133.yaml#L96

Does this mean no inflation or the assignment of zero obs error? Thanks!
