ASGARD Guided Mode
In addition to running an all-sky camera, the ASGARD software is also capable of detecting meteors in image-intensified imagery and controlling an optical-scanner (galvanometer + mirror tracking system) so that a second camera will follow the meteor in realtime.
Running ASGARD in guided mode on the correct hardware permits a wide range of studies, some of which are not possible with traditional video recordings:
The Canadian Automated Meteor Observatory (CAMO) is the first implementation to use the ASGARD software in guided mode. It is a project being run by Margaret Campbell-Brown and Paul Wiegert. The specifics of the hardware is summarised here:
The detection algorithm while running in guided mode is very similar to the one in all-sky mode, however the detection thresholds are dynamically computed to account for shot-noise present in the image-intensified imagery. With the above listed hardware, ASGARD is able to detect meteors down to magnitude +5.5 (and can calibrate against stars visible to magnitude ~+7.5).
Being able to guide the narrow field camera to look at a specific area in the wide field requires calibrating the hardware positioning. This is done by scanning out narrow field images which are rotated, scaled, and combined to give a mosaic. Matching stars can be found, and a plate mapping made.
