pynbody.plot.stars.mollview(map=None, fig=None, plot=False, filenme=None, rot=None, coord=None, unit='', xsize=800, title='Mollweide view', nest=False, min=None, max=None, flip='astro', remove_dip=False, remove_mono=False, gal_cut=0, format='%g', format2='%g', cbar=True, cmap=None, notext=False, norm=None, hold=False, margins=None, sub=None, return_projected_map=False)[source]#
Plot an healpix map (given as an array) in Mollweide projection.

Requires the healpy package.

This function is taken from the Healpy package and slightly modified.

Parameters:

  • map (float, array-like or None) – An array containing the map, supports masked maps, see the ma function. If None, will display a blank map, useful for overplotting.

  • fig (figure object or None, optional) – The figure to use. Default: create a new figure

  • plot (bool (default: False)) – if True the image is plotted

  • filename (string (default: None)) – Filename to be written to (if a filename is specified)

  • rot (scalar or sequence, optional) – Describe the rotation to apply. In the form (lon, lat, psi) (unit: degrees) : the point at longitude lon and latitude lat will be at the center. An additional rotation of angle psi around this direction is applied.

  • coord (sequence of character, optional) – Either one of ‘G’, ‘E’ or ‘C’ to describe the coordinate system of the map, or a sequence of 2 of these to rotate the map from the first to the second coordinate system.

  • unit (str, optional) – A text describing the unit of the data. Default: ‘’

  • xsize (int, optional) – The size of the image. Default: 800

  • title (str, optional) – The title of the plot. Default: ‘Mollweide view’

  • nest (bool, optional) – If True, ordering scheme is NESTED. Default: False (RING)

  • min (float, optional) – The minimum range value

  • max (float, optional) – The maximum range value

  • flip ({'astro', 'geo'}, optional) – Defines the convention of projection : ‘astro’ (default, east towards left, west towards right) or ‘geo’ (east towards right, west towards left)

  • remove_dip (bool, optional) – If True, remove the dipole+monopole

  • remove_mono (bool, optional) – If True, remove the monopole

  • gal_cut (float, scalar, optional) – Symmetric galactic cut for the dipole/monopole fit. Removes points in latitude range [-gal_cut, +gal_cut]

  • format (str, optional) – The format of the scale label. Default: ‘%g’

  • format2 (str, optional) – Format of the pixel value under mouse. Default: ‘%g’

  • cbar (bool, optional) – Display the colorbar. Default: True

  • notext (bool, optional) – If True, no text is printed around the map

  • norm ({'hist', 'log', None}) – Color normalization, hist= histogram equalized color mapping, log= logarithmic color mapping, default: None (linear color mapping)

  • hold (bool, optional) – If True, replace the current Axes by a MollweideAxes. use this if you want to have multiple maps on the same figure. Default: False

  • sub (int, scalar or sequence, optional) – Use only a zone of the current figure (same syntax as subplot). Default: None

  • margins (None or sequence, optional) – Either None, or a sequence (left,bottom,right,top) giving the margins on left,bottom,right and top of the axes. Values are relative to figure (0-1). Default: None

  • return_projected_map (bool) – if True returns the projected map in a 2d numpy array
