MomentMap#

class jdaviz.configs.cubeviz.plugins.moment_maps.moment_maps.MomentMap(*args, **kwargs)[source]#

Only the following attributes and methods are available through the public plugin API:

show()
open_in_tray()
close_in_tray()
dataset (DatasetSelect): Dataset to use for computing line statistics.
spectral_subset (SubsetSelect): Subset to use for the line, or Entire Spectrum.
continuum (SubsetSelect): Subset to use for the continuum, or None to skip continuum subtraction, or Surrounding to use a region surrounding the subset set in spectral_subset.
continuum_dataset (DatasetSelect): Dataset of the extracted 1D spectrum to use when visualizing the continuum. The continuum will be redetermined based on the input cube (dataset) when computing the moment map.
continuum_width: Width, relative to the overall line spectral region, to fit the linear continuum (excluding the region containing the line). If 1, will use endpoints within line region only.
n_moment
output_unit Choice of “Wavelength” or “Velocity”, applicable for n_moment >= 1.
reference_wavelength Reference wavelength for conversion of output to velocity units.
add_results (AddResults)
calculate_moment()

Public constructor
