Populations & objects
census: 513 targets x ~1h (LB,GT,JMG) MSPs (LB,GT,JMG,VK?,GS) spectra: 40 targets x 1h/month (LB,GT,JMG,AB,VK,GS) polarization: 150 targets x 1/3h (LB,JMG,AN) globular clusters: after census? check DM? (AP) elipsing binaries (black widows/redbacks) (RM,AP,JV)
with known eclipse: 5 targets x 3h (AB,RB?,RM,GS) without known eclipse (?) (AP)
FRBs (IC,JMG,AP) blind survey: later? strategy?

5
Populations & objects census: 513 targets x ~1h
all known pulsars with DM
-
6
Populations & objects spectra: 40 targets x 1h/month
spectral distribution study of the 40 'brightest' known pulsars (10 passes per pulsar within 6 months, 10-85 MHz)

Emission mechanisms
giants pulses: 5 targets (JMcK,JV) profile evolution: ~10 targets (LB,JMG,AB,MP) single-pulse polarization (AB,AN) drifting subpulses, mode switching, nulling (AB) single pulse: energy distribution, …: 7+ targets (AB,VK) single pulse multi-telescope: 12 sources x 2 x1/2h (GT,MP,JV,JMG,...)

Interstellar medium
FR variations → solar wind [feasible?] (CT?,JV) FR variations → ionosphere (AN) FR variations → ISM (AB,KMA,AN) DM variations → solar wind+CME (KMA,CT?,JV) DM variations → ISM (JMG,LB,JD,KMA,JMcK,GS,JV) scattering variation (JMG,AB,VK,KMA, JMcK,JV) scattering of giant pulses: 3 targets x 2h (AB,RM, JMcK, JV) VLBI of scattering screens: ~8 targets x 2h (RM, OW?) scintillation (JV,VK,RM)

fluxes polarization blind survey strategy
(subarraying? incoherent? antenna selection?) data volume piggyback (?) FRB search algorithm priorities
