This is a struct for our coarse channels

Fields

corr_chan_number: usize

Correlator channel is 0 indexed (0..N-1)

rec_chan_number: usize

Receiver channel is 0-255 in the RRI recivers

gpubox_number: usize

gpubox channel number This is better described as the identifier which would be in the filename of visibility files Legacy e.g. obsid_datetime_gpuboxXX_00 v2 e.g. obsid_datetime_gpuboxXXX_00

chan_width_hz: u32

Width of a coarse channel in Hz

chan_start_hz: u32

Starting frequency of coarse channel in Hz

chan_centre_hz: u32

Centre frequency of coarse channel in Hz

chan_end_hz: u32

Ending frequency of coarse channel in Hz

Implementations

impl CoarseChannel

pub fn get_fine_chan_centres_array_hz(
    mwa_version: MWAVersion,
    coarse_channels: &[CoarseChannel],
    fine_chan_width_hz: u32,
    num_fine_chans_per_coarse: usize
) -> Vec<f64>

Calculate the centre frequency of each fine channel of this coarse channel.

Arguments

• mwa_version - The version of the MWA is in use.

• coarse_channels - Vector of populated Coarse Channels.

• fine_chan_width_hz - Fine channel width in Hz.

• num_fine_chans_per_coarse - Number of fine channels per coarse channel.

Returns

• The centre frequency of the first fine channel of the coarse channel.
