(map=None, fig=None, rot=None, coord=None, unit='', xsize=200, ysize=None, reso=1.5, title='Gnomonic view', nest=False, remove_dip=False, remove_mono=False, gal_cut=0, min=None, max=None, flip='astro', format='%.3g', cbar=True, cmap=None, norm=None, hold=False, sub=None, margins=None, notext=False, return_projected_map=False)¶ Plot a healpix map (given as an array) in Gnomonic projection.
Parameters: - map : array-like
The map to project, supports masked maps, see the ma function. If None, use a blank map, useful for overplotting.
- fig : None or int, optional
A figure number. Default: None= create a new figure
- 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: 200
- ysize : None or int, optional
The size of the image. Default: None= xsize
- reso : float, optional
Resolution (in arcmin). Default: 1.5 arcmin
- title : str, optional
The title of the plot. Default: ‘Gnomonic view’
- nest : bool, optional
If True, ordering scheme is NESTED. Default: False (RING)
- min : float, scalar, optional
The minimum range value
- max : float, scalar, 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 roght, 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’
- 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 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
- notext: bool, optional
If True: do not add resolution info text. Default=False
- return_projected_map : bool
if True returns the projected map in a 2d numpy array
