pipeline.domain.spectralwindow.ChannelList

class ChannelList(chan_freqs: Sequence[int | float] | ArithmeticProgression, chan_widths: Sequence[int | float] | ArithmeticProgression, effbw: Sequence[int | float] | ArithmeticProgression)[source]

Bases: object

A container/generator for Channel objects.

A spectral window can contain thousands of channels. Rather than store all of these objects, a ChannelList generates and returns them lazily, on-demand.

Methods

__init__(chan_freqs: Sequence[int | float] | ArithmeticProgression, chan_widths: Sequence[int | float] | ArithmeticProgression, effbw: Sequence[int | float] | ArithmeticProgression) → None[source]

Initialize a ChannelList object.

Parameters:

  • chan_freqs -- Sequence or ArithmeticProgression of center frequency of channel (in Hertz) for all channels in ChannelList.

  • chan_widths -- Sequence or ArithmeticProgression of channel width (in Hertz) for all channels in ChannelList.

  • effbw -- Sequence or ArithmeticProgression of effective bandwidth (in Hertz) for all channels in ChannelList.
