Data Type
Units

 av:acquisition_frame_rate

Specifies the rate at which unique frames in a movie were acquired by the original camera. This may not match the video_frame_rate for a variety of reasons, for example removing frames or adding duplicate frames to make the movie play at a standard frame rate. If not present, the assumption is this matches the video_frame_rate.

Artemis Specific:
For Artemis, this is the rate of actual exposures by the camera. The GoPro-based cameras (e.g. SAW) generally acquired the data at 30 fps (but see intermediate_frame_rate).

ASCII_Real

Units_of_Frame_Rate

 img:active_flag

The active_flag attribute indicates whether or not the data processing described by the parent class is active. In general, the presence of the parent class implies it is active and thus active_flag is optional. The primary purpose for active_flag is to either explicitly indicate a correction is not active (for example, if it normally is but was explicitly turned off), or to be able to provide parameters for historical reasons that may no longer be relevant to a current correction.

Artemis Specific:
For Artemis, this is the scheduled mission activity, including lunar flyby targets and opportunistic imaging.
