4.39. photometry

Performs photometry using both sep and photutils.

Fits.photometry(xs: NUMERICS, ys: NUMERICS, rs: NUMERICS, headers: str | list[str] | None = None, exposure: str | float | int | None = None) → pd.DataFrame

Performs photometry using both sep and photutils.

Parameters

  • xs (Union[float, int, List[Union[float, int]]]):

    x coordinate(s) of the sources.

  • ys (Union[float, int, List[Union[float, int]]]):

    y coordinate(s) of the sources.

  • rs (Union[float, int, List[Union[float, int]]]):

    aperture radius(es) for the photometry.

  • headers (Union[str, list[str]], optional):

    Header keys to be extracted after photometry.

  • exposure (Union[str, float, int], optional):

    Header key that contains or a numeric value of exposure time.

Returns

pd.DataFrame

A DataFrame containing the photometric data.

Raises

  • NumberOfElementError

    Raised when the x and y coordinates do not have the same length.

4.39.1. Example:

from myraflib import Fits

fits = Fits.sample()

phot = fits.photometry([10, 10], [20 , 20], [10, 15, 16])
