Physical PropertiesΒΆ

Here is a list showing the physical properties which can be addressed in a query, and the respective abbreviation which is needed to be used in the pyilt2.query() function. One can access this mapping by either pyilt2.abr2prop or pyilt2.prop2abr.

To keep it simple, the same abbreviations are also used to restrict a search to a physical property (option: -p) with pyilt2report.
