Applications
The catalogue is used for a variety of purposes:
* Completeness assessments and statistical analysis
* Generation of H–R diagrams and definition of shortest period
* Computation of period & eccentricity
Eccentricity or eccentric may refer to:
* Eccentricity (behavior), odd behavior on the part of a person, as opposed to being "normal"
Mathematics, science and technology Mathematics
* Off-Centre (geometry), center, in geometry
* Eccentricity (g ...
