Power_law ( tuple ( float, float, float )) – The height of the scattering surface is a power-lawįunction, \(h(r) = a + b*(r/1\,\mathrm)^c\), With a power-law function or read from an input file (forĮxample returned by a radiative transfer code). Of radius in the disk midplane) that is either parameterized height of the scattering surface as function NoneType map_disk ( power_law : Tuple, radius : Tuple = (1.0, 500.0, 100), surface : str = 'power-law', filename : Optional = None ) → None #įunction for mapping a scattered light image to a height Methods Documentation deproject_disk ( ) → None #įunction for deprojecting a disk surface based on the mapping Map_disk(power_law)įunction for mapping a scattered light image to a height profile (i.e.įunction for extracting the phase function.įunction for correcting a scattered light image for the r^2 decrease of the stellar irradiation of the disk surface.įunction for creating a list with pixel values and creating a 2D array with the x and y pixel coordinates.įunction for estimating the (stellar irradiation corrected) total intensity image when fitsfile contains a polarized light image and image_type='polarized'.įunction for writing the available results to FITS files.
For example, the conversionįrom polarized to total intensity phase function is onlyįunction for deprojecting a disk surface based on the mapping of map_disk(). Image_type ( str) – Image type (‘polarized’ or ‘total’). Defined inĬounterclockwise direction with respect to the verticalĭistance ( float) – Distance between observer and star (pc). Pos_angle ( float) – Position angle of the disk (deg). Strongly compressed radii compared to the far side of the To be certain about using the correct near andįar side, it is best to check the _radius.fits file withĪ somewhat large inclination. Mapping can be exchanged by using a minus sign for the When using an inclination between 0 and 90 deg and using a The near side of the disk is on the right side of the image Inclination ( float) – Inclination of the disk (deg). Pixscale ( float) – Pixel scale of the image (arcsec per pixel). Parametersįitsfile ( str, np.ndarray) – Name of the FITS file with the scattered light image.Īlternatively, a 2D numpy array with the image can DiskMap ( fitsfile : Union, pixscale : float, inclination : float, pos_angle : float, distance : float, image_type : str = 'polarized' ) #Ĭlass for mapping a surface layer of a protoplanetary disk.
