FREQUENCY_AXIS |
function FREQUENCY_AXIS(data, [frame=string], [true_frame=variable]) |
Construct a frequency axis from a data structure.
Parameters | |
data |
The data structure to use in constructing a frequency axis. |
Keywords | |
frame |
The reference frame to use. If not supplied, the data.frequency_type value will be used. See frame_velocity for a full list of supported reference frames. |
true_frame |
The actual rest frame used in constructing the frequency axis. The only way this will not equal the frame argument is if that argument was invalid. In that case, this keyword will be the same as the frame in data.frequency_type. |
