## Direction-dependent frequency measurements
Study the directional response of atomic clocks or optical apparatus in a motion background. First specify transfer functions, background-velocity conventions and daily or turntable modulation. Do not publish a fixed amplitude without an apparatus derivation.
## Moving charges and precise orbits
High-speed source fields with probe response, and higher-order orbital terms, may offer tests. Use original data and their error structure; another theory's fitted parameters are not original observations.
## Free longitudinal spatial waves
Specify response features distinct from known thermal, acoustic and electromagnetic noise and a joint emission, propagation and detection model.
## Requirements for a proposal
Specify ASD and comparison signals, their difference, precision, major systematics and available data. These directions are still proposals and modeling tasks.
