nenupy.observation.obs_config.PulsarFoldConfig

class nenupy.observation.obs_config.PulsarFoldConfig(_setFromParset=False, **kwargs)[source]

Bases: _UnDySPuTeDConfig

UnDySPuTeD Pulsar-FOLD mode observation configuration.

Parameters:

nSubBands (int) – Number of sub-bands (min: 1, max: 192, default: 192).
nPolars (int) – Number of polarizations (min: 1, max: 4, default: 4).
tFold (float or TimeDelta) – Pulsar time fold in seconds (min: 5.36870912, max: 21.47483648, default: 10.73741824).
nBins (int) – Number of bins (min: 16, max: 8096, default: 2048).
durationSec (int or TimeDelta) – Observation duration in seconds (default: 0).

Added in version 1.2.0.

`durationSec`
`freqRes`
`nBins`
`nBits`
`nChannels`
`nMAs`
`nPolars`
`nSubBands`
`tFold`
`timeRes`
`volume`	Computes an estimation of the data volume of an UnDySPuTeD Pulsar-FOLD observation file.
