    o VLA Sources
      Indicate the sources, including their Right Ascension and
      Declination (if not specified elsewhere), to be observed with
      the VLA.  Also indicate which sources are to be grouped together
      into observing sessions.

    o VLA Sensitivity (for more details, see https://go.nrao.edu/ect)
      What are the required VLA on-target-source time and sensitivity
      (the RMS noise level) to achieve the science goal?

    o VLA Scheduling
      Please detail any scheduling constraints. For example: Do the
      VLA observations need to be coordinated with Swift or another
      telescope? If this is monitoring, what is the cadence?

     3 mm (W-band)

   o  VLBA Stations (https://go.nrao.edu/vlba-sites)
      Specify the minimum number of VLBA stations acceptable, and if
      any of the ten VLBA stations are required.

   o VLBA Sources
     Indicate the sources, including their Right Ascension and
     Declination (if not specified elsewhere), to be observed with the
     VLBA.  Also indicate which sources are to be grouped together
     into observing sessions.

   o VLBA Sensitivity (for more details, see https://go.nrao.edu/vlba-expcalc)
     What are the required VLBA on-target-source time and sensitivity
     (the RMS noise level) to achieve the science goal?

   o VLBA Scheduling
     Please detail any scheduling constraints. For example: Do the
     VLBA observations need to be coordinated with Swift or another
     telescope? If this is monitoring, what is the cadence?
