healpy.projaxes.SphericalProjAxes

class healpy.projaxes.SphericalProjAxes(ProjClass, *args, **kwds)

Define a special Axes to take care of spherical projection.

Parameters:

projection : a SphericalProj class or a class derived from it.

type of projection

rot : list or string

define rotation. See rotator.

coord : list or string

define coordinate system. See rotator.

coordprec : number of digit after floating point for coordinates display.

format : format string for value display.

Notes

Other keywords from Axes (see Axes).

Methods

delgraticules()	Delete all graticules previously created on the Axes.
format_coord(x, y)	Format the coordinate for display in status bar.
get_lonlat(x, y)	Get the coordinate in the coord system of the image, in lon/lat in deg.
get_meridian_interval(vx[, vy, vz])	Get the min and max value of phi of the meridians to cover the field of view.
get_parallel_interval(vx[, vy, vz])	Get the min and max value of theta of the parallel to cover the field of view.
get_value(x, y)	Get the value of the map at position x,y
graticule([dpar, dmer, coord, local, verbose])	Draw a graticule.
projmap(map, vec2pix_func[, vmin, vmax, ...])	Project a map on the SphericalProjAxes.
projplot(*args, **kwds)	projplot is a wrapper around matplotlib.Axes.plot() to take into account the
projscatter(theta[, phi])	Projscatter is a wrapper around matplotlib.Axes.scatter() to take into account the spherical projection.
projtext(theta, phi, s, **kwds)	Projtext is a wrapper around matplotlib.Axes.text() to take into account the spherical projection.
set_coordprec(n)	Set the number of digits after floating point for coord display.
set_format(f)	Set the format string for value display
