Spectrum structure¶
Getting started¶
Attributes of the ‘Spec’ object¶
Attribut |
What is it? |
|---|---|
Spec.wvs |
The wavelength values of the spectrum. |
Spec.values |
The brightness surface or flux values of the spectrum. |
Spec.units |
The unit of the y axis values of the spectrum. |
Spec.dwvs |
Interval between two points on the wavelength axis, in µm. |
Methods of the ‘Spec’ object¶
Method |
What does it do? |
|---|---|
Spec.convert() |
Convert spectrum values into another unit (‘MJy/sr’, ‘Jy’, ‘erg s-1 cm-2 Hz-1’, ‘erg s-1 cm-2 um-1’, ‘erg s-1 cm-2 um-1 sr-1’). |
Spec.cut() |
Extract a part of the spectrum using limits of the requiered interval. |
Spec.sub_baseline() |
Subtracts a baseline by fitting a polynomial around an emission line. |
Spec.line_integ() |
Computes the integrated flux or surface brightness of a line. |
Spec.line_velocity() |
Calculates the Doppler shift of an emission line using Gaussian profile fitting. |
Spec.copy() |
Copy a spectrum. |
