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).
