Summary of comet parameters computed by OpenComet. Three measures are given to assess DNA damage (Tail DNA%, tail moment and Olive moment) along with other useful shape and intensity measurements.

Parameter	Description	Parameter	Description
Comet area	Number of pixels in the comet	Head DNA%	Head DNA content as a percentage of comet DNA content
Comet length	Length of the comet region in pixels	Tail area	Number of pixels in the tail
Comet DNA content	Sum of pixel intensities inside the comet	Tail length	Length of the tail in pixels
Comet average intensity	Comet DNA content divided by comet size	Tail DNA content	Sum of pixel intensities inside the tail
Head area	Number of pixels inside the head	Tail average	Tail DNA content divided by tail size
Head diameter	Length of the head in pixels	Tail DNA%	Tail DNA content as a percentage of comet DNA content
Head DNA content	Sum of pixel intensities inside the head	Tail moment	Tail length times Tail DNA%
Head average intensity	Head DNA content divided by head size	Olive moment	Product of tail DNA% and the distance between the intensity-weighted centroids of head and tail
