comply with the Open Source
Definition — in brief, they allow
software to be freely used, modified,
and shared. To be approved by the
Open Source Initiative (also known as
the OSI), a license must go through the
Open Source Initiative's license review
process.

Q
Quality Score
A measure of the quality of an HR
detection, where 10 is excellent and 1

to assist with filtering false detections
out of a dataset. Detections with a
quality score < 3 are filtered out upon
export to CSV when using the Export
Data application (HR detections on
HR2 receivers only)
