icecube.radcube.SpikeFilter module¶
- class icecube.radcube.SpikeFilter.SpikeFilter(filename='')¶
Bases:
object
Applies a filter to remove frequency-domain RFI spikes Spike filters are applied per-antenna-channel and must be tuned properly.
- Parameters:
filename (str, optional) – Path to spike filter file
- ApplyFilter(inputSpec, antkey, chkey, power=2)¶
Applies the spike filter to the passed in radio spectrum to remove RFI
- Parameters:
inputSpec – A
icecube.dataclasses.AntennaSpectrum
object to be reweightedantkey – The
icecube.dataclasses.AntennaKey
corresponding to which filter file to use to reweight the waveformchkey – The channel key corresponding to which filter file to use to reweight the waveform
power – The number of times to apply the filter. Zero does nothing and it is recommended to use at least 1.
- Returns:
A copy of the waveform with the filter applied.
- GetFreqs()¶
- GetGains(antkey, chkey)¶
- HasKey(antkey, chkey)¶
- LoadData(filename)¶
Loads up the ASCII spike filter file
- Parameters:
filename – Location of the file with the spike filter information
- SaveData(filename, freqs, gains)¶
Saves an ASCII file of the filters :param filename: Name of ASCII file to save to :param freqs: List of frequency values for the corresponding filter :param gains: Dict of the gain values. Keys should be (AntennaKey, ChannelKey). Entries should be array of gain values
