edges_cal.tools.FrequencyRange

class edges_cal.tools.FrequencyRange(f: tp.FreqType, *, f_low: tp.FreqType = <Quantity 0. MHz>, f_high: float = <Quantity inf MHz>, bin_size=1, alan_mode=False, post_bin_f_low: tp.Freqtype = <Quantity 0. MHz>, post_bin_f_high: float = <Quantity inf MHz>)

Class defining a set of frequencies.

A given frequency range can be cut on either end, and be made more sparse.

Parameters:

• f – An array of frequencies defining a given spectrum.

• f_low – A minimum frequency to keep in the array. Default is min(f).

• f_high – A minimum frequency to keep in the array. Default is min(f).

• bin_size (int) – Bin input frequencies into bins of this size.

• alan_mode (bool) – Only applicable if bin_size > 1. If True, then take every bin_size frequency, starting from the 0th channel. Otherwise take the mean of each bin as the resulting frequency.

Methods

__init__(f, *[, f_low, f_high, bin_size, ...])	Method generated by attrs for class FrequencyRange.
clone(**kwargs)	Make a new frequency range object with updated parameters.
denormalize(f)	De-normalise a set of frequencies.
from_edges([n_channels, max_freq, ...])	Construct a FrequencyRange object with underlying EDGES freqs.
normalize(f)	Normalise a set of frequencies.
with_new_mask(**kwargs)	Make a new read-only frequency range object with the same freqs.

Attributes

center	The center of the frequency array.
df	Resolution of the frequencies.
freq	The frequency array.
freq_full	Alias for f.
freq_recentred	The frequency array re-centred so that it extends from -1 to 1.
mask	Mask used to take input frequencies to output frequencies.
max	Maximum frequency in the array.
min	Minimum frequency in the array.
n	The number of frequencies in the (masked) array.
range	Full range of the frequencies.
