I have a list of geological data. The data is for 3 variables: member, level and L+/-

These variables correspond to a particular position on a stratigraphic column/chart.

I would like help with precisely knowing which level -3 refers to? Is it the level 3 units from the bottom of the column upwards, or from the top of the column downwards? Thank you.
