Subject:
OLI/MASC/M1 - False triggering of cameras
DataStreams:olimascM1.00, olimascM1.b1, olimascM1.a1
Description:
Radar RF pollution causing a high frequency false triggering (black images) of the MASC 
cameras, power outages at the site, and heat pad power problems as well as IR sensor 
sensitivity problems caused an abundance of MASC imagery without any information.
Suggestions: 
Please use images with only one particle present. To avoid checking black images you 

can (1) select only images with reasonable fall speeds, and (2) omit all images with 
less than ~50 KB.
