Dear All,
             Hello. I'm new to the list but have used ImageJ for a while
now, mainly on geomorphic data, and  have found it to be an excellent
programme. I've currently begun to use ImageJ to analyse my archery ends
to obtain the distance from the centre of the target face and angle from
the vertical of the arrows I have shot. I use the measuring tools for
this, namely the Angle tool and Straight Line Selection tool. However
I've noticed that the angle tool does not directly measure a full 360
degrees but measures up to 180 degrees and then decreases again. I
understand this is surmountable with some simple mathematics but this
slows down my data entry and analysis somewhat! I've searched the forum
and the ImageJ documentation but am no further to finding a solution.
Could anyone offer any solutions to my problem? Thanks very much in
advance for any help.

Best wishes,
Gareth.
