Notes

Issues

• delay model

  • introduce extra parameters: h-delay v-delay niao-x niao-y
  • solve for antenna locations, NIAO, fixed delays separately (dual-pol)
  • replace DB proxy functionality (delay, delay-rate, fringe, fringe-rate)

• Target

  • refactoring
  • objectify for ease of backends?
  • new enu target

• Flux Density Model

  • separate file
  • origin tags
  • frequency calculations (doppler km/s -> Hz)
  • new models:
    • cont [origin] min max a b c d e f
    • line [origin] (name velocity-from velocity-to jy)+
    • sat [origin] (center bw jy)+

• Source model

  • basic size (disk model)

• Antenna

  • extra parameters

• Beam model

  • cos^3 or gaussian

• Catalogue

  • creation: from filename in addition to file object
  • add + add_tle?
  • historical TLE database
  • search for flux limit based on beam model and separation

• projections

  • Mattieu's projection (slant azimuthal?)
  • integrate wcslib (astropy?)

• Backends

  • need celestial->terrestrial, projections, uvw, TLEs
  • abstracted bodies (directions), observers (positions), timestamps (epochs)
  • pyrap / astropy / CALC
