class baseband_tasks.io.psrfits.PSRFITSReader(ih, *, dtype=None, weighted=True, **kwargs)

Bases: BaseTaskBase

Wrapper for reading PSRFITS HDUs.

Parameters:

ihwrapped PSRFITS HDU

The input fits table HDU, wrapped in an interface from psrfits.

dtypedtype, optional

Dtype of the samples. Default: inferred from hdu.

weightedbool, optional

Whether to weight the data along the frequency axis using the ‘DAT_WTS’ column. Default of True should suffice for most purposes, but sometimes the weights are incorrect.

— **kwargsmeta data for the stream, which usually include

frequencyQuantity, optional

Frequencies for each channel. Should be broadcastable to the sample shape. Default: inferred from hdu.

sidebandarray, optional

Whether frequencies are upper (+1) or lower (-1) sideband. Should be broadcastable to the sample shape. Default: inferred from hdu.

polarizationarray or (nested) list of char, optional

Polarization labels. Should broadcast to the sample shape, i.e., the labels are in the correct axis. For instance, ['X', 'Y'], or [['L'], ['R']]. Default: inferred from hdu.
