Non official zpt functions in RedClump_GSP-Spec_SF.ipynb

docs/notebooks/RedClump_GSP-Spec_SF.ipynb

In this notebook we use probably the non-official zeropoint package. The API of the official one differs.

from astroquery.gaia import Gaia
from zero_point import zpt

# Necessary line in the new API
zpt.load_tables()

# get some dummy data
query = r"""select * from gaiaedr3.gaia_source
where phot_g_mean_mag between 17.9 and 18.1
and random_index between 700000000 and 700001000
and (astrometric_params_solved = 31 or astrometric_params_solved = 95)
"""

data = Gaia.launch_job(query).get_results().to_pandas()

gmag = data['phot_g_mean_mag'].values
nueffused = data['nu_eff_used_in_astrometry'].values
psc = data['pseudocolour'].values
ecl_lat = data['ecl_lat'].values
soltype = data['astrometric_params_solved'].values  

# one line to rule them all in one shot. (no more zpt4 or zpt5)
zpvals = zpt.get_zpt(gmag, nueffused, psc, ecl_lat, soltype)
