Select from Solicitation definition

Allocation Requests

Create 1 to 3 Allocation Requests and randomly select the Facility from the ones defined in the Solicitation.

restricted to VLA, GBT

Capability Request per Allocation Request

Per Allocation Request, create 1 2 to 3 10 Capability Requests. The Capability should be randomly selected from what is available for the Facility in the Solicitation.

restricted to VLA Continuum, GBT Spectral Line

Field Sources per Capability Request

Per Capability Request, randomly select between 1 to 3 Test Field Sources available to the Capability.

Use calibratorList.json to select 1 to 3 field source + spectral spec pairs per Capability Request

If VLA Continuum

  • set other parameters to 0 if not specified in json

If GBT Spectral Line

  • set Peak Line Flux Density to 10% of peak continuum flux density
  • set Line Width to 50 km/s
  • set other parameters to 0 if not specified in json

Spectral Specifications per Capability Request

Per Capability Request, randomly select between 1 to 3 1  Test Spectral Specifications available to the Capability.

see above for center frequency

If VLA Continuum

  • set spectral resolution 1000 km/s
  • set bandwidth to 2000 km/s

If GBT Spectral Line

  • set spectral resolution to 10 km/s
  • set bandwidth to 300 km/s


Performance parameters per Capability Request

Per Capability Request, randomly select a set Test Performance ParameterParameters

If VLA Continuum:

  • randomly select a desired VLA Configuration from the ones available in the Capability (A, B, C, D), once a config is selected B_max and B_min is defined
    • B_max = (36.4, 11.1, 3.4, 1.03) km
    • B_min = (0.68,0.21,0.035,0.035) km
  • calculate Angular Resolution as 
    θ = 1.2(c_km/freq_Hz)/B_max where
    c is the speed of light = 2.998e5 km/s
  • calculate
  • set Angular Resolution as
  • set largest angular scale as
    θ = (c_km/freq_Hz)/B_min where
  • set RMS sensitivity as 10% of the peak continuum flux density

If GBT Spectral Line

  • set calculate the Angular Resolution as
    θ = 1.2(c_km/freq_Hz)/D
    where D = 0.1 km
  • set RMS Sensitivity as 30% of the peak line flux density

Calibration parameters per Capability Request

Per Capability Request, randomly select a Test Calibration Parameter

If VLA Continuum:

  • randomly set Polarization Calibration boolean to True

If GBT Spectral Line:

  • randomly set Flux Density Calibration to True
  • randomly set Test Source to True
  • randomly set Polarization Calibration to True
