Accepted keys in the configuration dictionary#

bandwidth#: Type: float

The bandwidth for the display, in km/s.

components#: Type: dict

A dictionary giving the information on the components.

data_file#: Type: str

The path to the data file.

df_mhz#: Type: float

The frequency spacing in MHz when computing a model alone.

fit_freq_except#: Type: list

A list of 2-element lists containing the min and max frequencies to avoid when fitting.

Note

This is a mandatory keyword when fitting an entire spectrum. It can be an empty list.

franges_ghz#: Type: list

A list of 2-element lists containing the min and max frequencies for all ranges the user wants to select.

inspect#: Type: list

The list of tags of the species of interest.

line_shift_kms#: Type: float

For data in sky frequency scale, the velocity shift in km/s to take into account when searching transitions.

max_iter#: Type: int

The maximum number of iterations for the minimization. Default depends on the chosen algorithm.

minimize#: Type: bool

Whether to minimize or not.

noise_mk#: Type: float

Default: 0.

The noise in mK when computing a model alone.

output_dir#: Type: str

The path to the directory where the files created by the program will be saved.

oversampling#: Type: int or float

Oversampling used to display the model. Default : 1

plot_gui#: Type: bool

Default: True

Whether to display on screen.

plot_pdf#: Type: bool

Default: False

Whether to create a pdf file for the display.

rms_cal#

snr_threshold#: Type: int or float

The cut-off in signal-to-noise ratio (SNR) to save a given transition in a CASSIS linelist. The SNR is computed on the modeled intensities.

tc#: Type: float or str

Default: 0.0

The continuum in data units. Can be a single value of a two-column file with frequency and continuum values.

tcmb#: Type: float

Default: 2.73

The temperature in K of the CMB.

thresholds#: Type: dict or str

Default: no thresholds

A dictionary or a path to a valid file containing the thresholds on spectroscopic parameters (see Thresholds).

tuning_info#: Type: dict

A dictionary providing the lists of frequency ranges (values) for the telescope(s) used in the observations (keys).

v_range#: Type: dict or str

A dictionary or a path to a valid file containing velocity ranges to be displayed (see Velocity ranges).
