EmFit¶
Overview¶
EmFit is a Python-based emission-line fitting code for fitting H𝛽, [OIII]4959,5007, [NII]6548,6583, H𝛼, and [SII]6716,6731 emission lines in low-redshift (z ≤ 0.45) sources.
It includes testing for extra components for [OIII], [SII], and Halpha. The code is available here.
If you use this catalog and/or the EmFit code, please cite Pucha et al. (2025) and Pucha et al. (in preparation).
Caution
We recently identified a bug in the EmFit code that led to an underestimation of the error spectrum,
which is utilized in both determining the best-fit model and for estimating the uncertainties in the emission-line measurements.
A fix is currently in progress, and an updated catalog will be released soon as v2.3.
Preliminary tests show that for over 95% of the targets, the line flux and line width (sigma) values will change by less than 1%.
However, the revised measurement error values may change. In some cases, the final best-fit might also differ in the number and
nature of the emission-line components.

Change Log¶
v2.2¶
Initial catalog - based on EmFit tag v2.2.0
v2.3¶
- Based on
EmFittag v2.3.0 - Fixed a bug related to the input error spectrum, where the
ivararray is now corrected for MW dust extinction. - Improved emission-line measurements and uncertainties.
- Updated catalog to be released soon.
