This page stores the change log for pysme since May 2024.

In-development#

(build) from v0.6.27, wheel builds bundle SMElib and _smelib binaries instead of relying on first-import runtime download/compile.
(model) modify the atmosphere geometry to ‘’ for auto desicion instead of ‘PP’.
(sme structure) add sme.wint as a segment-aware optional transfer grid input for synthesis.
(synthesize) when sme.wint is provided, synthesis now prefers user-provided wint over internal cached wavelength grids.
(docs) update long-spectrum examples to prefer linelist_mode='dynamic' (keep auto as deprecated compatibility alias).

(synthesize) synthesize function now support calculating line central-depth and line range, and can use it to select only the relevant lines in synthesize (and thus in solve).
- Available in both LTE and NLTE calculation.
(solve) dynamic parameter function now support abundances.

(vald) add save and merge function to ValdFile.
- Coupling information (‘LS’, ‘JK’ etc) are missed during reading. Now added back.
- There is no vmic column in VALD short extract_all mode, but pysme have. This leads to I/O fail for this kind of line list. Fixed.

(mask) revert mask function back. The modification in v0.4.180 caused a bug on mask and it is fixed now.
(synthesize) fix the vstep issue when synthesizing sparce spectrum.
(nlte) add ResetDepartureCoefficients function to ensure correct NLTE calculation
(solve) use ‘vrad’ instead of ‘v_rad’ for the radial velocity fitting.
(solve) add dynamic parameter function; sme parameter can changes according to other parameters while not being included in the fitting.
New readthedocs theme (alabaster -> sphinx_book_theme).

~~fix mask bug. The continuum fitting function is now available.~~ (see v0.4.183)
