TableInterpolator

class ctapipe.utils.TableInterpolator(filename, verbose=1)

Bases: object

This is a simple class for loading lookup tables from a fits file and interpolating between them

Methods Summary

interpolate(params, pixel_pos_x, pixel_pos_y)
interpolated_image(params)	Function for creating a ful interpolated image template from the interpolation library
parse_fits_table(filename)	Function opens tables contained within fits files and parses them into a format recognisable by the interpolator.

Methods Documentation

interpolate(params, pixel_pos_x, pixel_pos_y)

Parameters:

params: ndarray

numpy array of interpolation parameters currently [energy, impact distance, xmax]

pixel_pos_x: ndarray

pixel position in degrees

pixel_pos_y: ndarray

pixel position in degrees

Returns:

ndarray of expected intensity for all pixel positions given

interpolated_image(params)

Function for creating a ful interpolated image template from the interpolation library

Parameters:

params: ndarray

numpy array of interpolation parameters currently [energy, impact distance, xmax]

Returns:

ndarray of a single image template

parse_fits_table(filename)

Function opens tables contained within fits files and parses them into a format recognisable by the interpolator.

Parameters:

filename: str

Name of table file

Returns:

tuple (grid points, bin centres, images)
