Author:

WataruKawasaki

Message:

New Development: Yes

JIRA Issue: Yes (CAS-1800 + CAS-1807)

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed: added parameters fitfunc for sdfit and clip, clipmaxmin, clipoutside for sdflag

Test Programs:

Put in Release Notes: No

Module(s): sdfit, sdflag

Description: Added a parameter for enabling Lorentzian line fitting with sdfit, and parameters for y-axis clipping with sdflag. Also 4 files for Lorentzian function class are (Lorentzian1D*) added.
