threeML.plugins.PhotometryLike module

class threeML.plugins.PhotometryLike.BandNode(name, index, value, mask)

Bases: object

property off

‘p.off = True’ or ‘p.off = False’.

Type:

Turn on or off the band. Use booleans, like

property on

‘p.on = True’ or ‘p.on = False’.

Type:

Turn on or off the band. Use booleans, like

class threeML.plugins.PhotometryLike.PhotometryLike(name: str, filters: FilterSequence | FilterResponse, observation: PhotometericObservation)

Bases: XYLike

display_filters()

display the filter transmission curves

Returns:

classmethod from_file(name: str, filters: FilterResponse | FilterSequence, file_name: str)

Create the a PhotometryLike plugin from a saved HDF5 data file

Parameters:

• name – plugin name

• filters – speclite filters

• file_name – name of the observation file

classmethod from_kwargs(name, filters, **kwargs)

Example:

grond = PhotometryLike.from_kwargs(‘GROND’,

filters=threeML_filter_library.ESO.GROND, g=(20.93,.23), r=(20.6,0.12), i=(20.4,.07), z=(20.3,.04), J=(20.0,.03), H=(19.8,.03), K=(19.7,.04))

Magnitudes and errors are entered as keyword arguments where the key is the filter name and the argument is a tuple containing the data. You can exclude data for individual filters and they will be ignored during the fit.

NOTE: PhotometryLike expects apparent AB magnitudes. Please calibrate your data to this system

Parameters:

• name – plugin name

• filters – speclite filters

• kwargs – keyword args of band name and tuple(mag, mag error)

property magnitude_errors

property magnitudes

property observation: PhotometericObservation
