Cartoon of DM cumulative

Plot of increasing DM from Earth to the FRB

Args:

  • ax1 (matplotlib.Axis) – First axis. Used for Milky Way and local group

  • ax2 (matplotlib.Axis) – Second axis. Used for Cosmic and Host

  • coord (astropy.coord.SkyCoord) – Coordinate of the FRB used with ne2001

  • zFRB (float) – Redshift of the FRB

  • halos (?, optional) – Not implemented!

  • host_DM (float) – DM to use for the Host

  • ymax (tuple or list) – ymin, ymax values for the y-axis

  • IGM_only (bool, optional) – Use only the IGM for DM_Cosmic, i.e. ignore the presumed average halo contribution

  • show_M31 (bool, optional) – Include M31 in the calculation? NOT IMPLEMENTED RIGHT NOW

  • fg_halos (dict or Table) – Used to add to DM_IGM Keys must include ‘z’ ‘DM’ ‘lbl’

  • smin (float, optional) – Minimum value in axis2 (Gpc)

  • dsmx (float, optional) – Padding on the x-axis; Gpc Allows for host. Set to 0 to ignore host

  • FRB_DM (float) – Observed value; sets ymax = FRB_DM+50

  • yscl (float, optional) – Controls placement of labels

  • cosmo (astropy.cosmology, optional) – Defaults to Repo Cosmology

Args:

  • frbs (list) – list of FRB objects

  • clrs (list, optional)

  • outfile (str, optional)

  • multi_model (deprecated)

  • no_curves (bool, optional) – If True, just show the data

  • F (float, optional) – Feedback parameter

  • widen (bool, optional) – If True, make the plot wide

  • show_nuisance (bool, optional) – if True, add a label giving the Nuiscance value

  • show_sigmaDM (bool, optional) – If True, show a model estimate of the scatter in the DM relation

  • cl (tuple, optional) – Confidence limits for the scatter

  • beta (float, optional) – Parameter to the DM scatter estimation

  • gold_only (bool, optional) – If True, limit to the gold standard sample

  • gold_frbs (list, optional) – List of gold standard FRBs

  • ax (matplotlib.Axis, optional) – Use this axis instead of creating one

  • zmax (float, optional) – Max redshift for the MR line

  • cosmo (astropy.cosmology, optional) – Defaults to Repo Cosmology

Returns:

ax (optional): if outfile is None

Return type:

dict
