Functions

get_CCFs(planet_params, stellar_params[, ...])

Fetch ESPRESSO white-light CCFs data.

get_spectra([directory_path, day, ...])

Fetch ESPRESSO spectra.
get_CCFs(planet_params: dict, stellar_params: dict, directory_path: str = '/home/telmo/phd_seminar/Eduardos_code/white_light_ccfs/', day: str = '2021-08-11', index_to_remove: str = 'last', plot: bool = True)[source]

Fetch ESPRESSO white-light CCFs data.

Parameters:

  • planet_params (dict) – dictionary containing the following planetary parameters: orbital period, system scale, planet-to-star radius ratio, mid-transit time, eccentricity, argument of periastron, planetary inclination and spin-orbit angle.

  • stellar_params (dict) – dictionary containing the following stellar parameters: effective temperature and error, superficial gravity and error, metallicity and error.

  • directory_path (str) – path where the white light CCFs are stored.

  • day (str) – in case where the target was observed in more than one night, choose the one to use.

  • index_to_remove (str) – in case the user wants to remove a given CCF a priori.

  • plot (bool) – whether to plot the CCF profiles colored by orbital phase.

Returns:

  • CCFs (numpy array) – matrix with the CCF profiles (RV, flux and flux error), with shape (N_CCFs, 3, N_points).

  • time (numpy array) – time of observations in BJD.

  • airmass (numpy array) – airmass at the time of observation.

  • berv (numpy array) – BERV at time of observation.

  • bervmax (numpy array) – maximum BERV.

  • snr (numpy array) – signal-to-noise ratio of observation.

  • list_ccfs (str) – list of CCFs file path and names.

get_spectra(directory_path: str = '/home/telmo/phd_seminar/Eduardos_code/telluric_corrected_spectra/', day: str = '2021-08-11', type_spec: str = 'SKY', index_to_remove: str = 'last')[source]

Fetch ESPRESSO spectra.

Parameters:

  • directory_path (str) – path where the spectra are stored.

  • day (str) – in case where the target was observed in more than one night, choose the one to use.

  • type_spec (str) – type of spectra to be retrieved (e.g., S1D_TELL_CORR_A).

  • index_to_remove (str) – in case the user wants to remove a given spectra a priori.

Returns:

  • spectra (numpy array) – matrix with the spectra (wavelenth in air, flux, flux error and quality flag), with shape (N_spectra, 4, N_pixels).

  • time (numpy array) – time of observations in BJD.

  • airmass (numpy array) – airmass at the time of observation.

  • berv (numpy array) – BERV at time of observation.

  • bervmax (numpy array) – maximum BERV.

  • snr (numpy array) – signal-to-noise ratio of observation.

  • rv (numpy array) – radial velocity of observation.

  • list_spectra (str) – list of spectra file path and names.
