measure_source_fwhm

sitelle.source.measure_source_fwhm(detection, data, rmax=10)

TO USE CAREFULLY Function used to estimate the FWHM of a source. It performs aperture photometry with inscreasing radius from the source position, and then, tries to find where half of the maximum of flux is reached.

Parameters:
  • detection (Series) – Row of a DataFrame containing detected sources. Should have columns xcentroid and ycentroid, in classic convention (not astropy)
  • data (2D ndarray) – Flux map used for the photometry
