ftsdata.OneSidedOpdData

class ftsdata.OneSidedOpdData(*args, hits=<object object>, **kwargs)

Interferogram cube with the ZPD at the start of the OPD axis.

Only positive OPDs are stored. The spectrum is obtained by an inverse real FFT, see to_spectra().

__init__(*args, hits=<object object>, **kwargs)

Methods

__init__(*args[, hits])
add(operand[, operand2])	Performs addition by evaluating self + operand.
convert_unit_to(unit[, equivalencies])	Returns a new NDData object whose values have been converted to a new unit.
divide(operand[, operand2])	Performs division by evaluating self / operand.
from_array(opd, data[, hits, mask])	Construct FTS data from arrays.
get_axis_from_repr(plane)	Retrieve data axis from representation
max(**kwargs)
mean(**kwargs)
min(**kwargs)
mip([axes, level, attr])	Return a 'Multum In Parvo' of a given level on the data along given axes.
multiply(operand[, operand2])	Performs multiplication by evaluating self * operand.
opd_trim([fraction])
subtract(operand[, operand2])	Performs subtraction by evaluating self - operand.
sum(**kwargs)
to_dset([dset_mask, dset_uncertainty, ...])	Create the IDIA HDF5 datasets and attributes from a FTSData object.
to_hdu([hdu_data, hdu_mask, ...])	Creates an HDUList object from a FTSData object.
to_spectra([apodization, output_shape, ...])	Invert a one-sided interferogram cube.
