GaiaDR3XPspectracorrectionV1 is an astronomy Python package to provide a correction for the Gaia DR3 XP spectra. The corrected spectra can significantly eliminate the systematic errors of the original Gaia DR3 XP spectra, please refer to our paper (Huang et al. 2024) for more details.
We can give robust corrections for sources in the roughly following range: −0.5 < BP − RP < 2 3 < G < 17.5 E(B − V) < 0.8 Sources that do not fall into this range are not tested for the correctness of the corrections given by the correction package.

Correction for one spectrum
from GaiaDR3XPspectracorrectionV1 import Gaia_Correction_V1 [flux_out,caution,C2,C3] = Gaia_Correction_V1.correction(flux_origin,G,error,Truncation=False,absolute_correction=True)
