photometry

boulliau.photometry(image_paths, master_dark_path, master_flat_path, star_positions, aperture_radii, centroid_stamp_half_width, psf_stddev_init, aperture_annulus_radius)

Parameters:

master_dark_path : str

Path to master dark frame

master_flat_path :str

Path to master flat field

target_centroid : ndarray

position of centroid, with shape (2, 1)

comparison_flux_threshold : float

Minimum fraction of the target star flux required to accept for a comparison star to be included

aperture_radii : ndarray

Range of aperture radii to use

centroid_stamp_half_width : int

Centroiding is done within image stamps centered on the stars. This parameter sets the half-width of the image stamps.

psf_stddev_init : float

Initial guess for the width of the PSF stddev parameter, used for fitting 2D Gaussian kernels to the target star’s PSF.

aperture_annulus_radius : int

For each aperture in aperture_radii, measure the background in an annulus aperture_annulus_radius pixels bigger than the aperture radius
