  We present Version 2023-02-04 (ISO) of the Chroma+ atmospheric, spectrum, and
transit light-curve modelling suite, which incorporates the VALD atomic line
list. This is a major improvement as the previous versions used the much
smaller NIST line list. The NIST line list is still available in Chroma+ for
those projects requiring speed over completeness of line opacity. We describe a
procedure for exploiting the ''Array job'' capability of the slurm workload
manager on multi-cpu machines to compute broadband high resolution spectra with
the VALD line list quickly using the Java version of the code (ChromaStarServer
(CSS)). The inclusion of a much larger line list more completely allows for the
many weaker lines that over-blanket the blue band in late-type stars and has
allowed us to reduce the amount of additional ad hoc continuous opacity needed
to fit the solar spectral energy distribution (SED). The additional line
opacity exposed a subtle bug in the spectrum synthesis procedure that was
causing residual blue line wing opacity to accumulate at shorter wavelengths.
We present our latest fits to the observed solar SED and to the observed
rectified high resolution visible band spectra of the Sun and the standard
stars Arcturus and Vega. We also introduce the fully automated Burke-Gaffney
Observatory (BGO) at Saint Mary's University (SMU) and compare our synthetic
spectra to low resolution spectra obtained with our grism spectrograph that is
available to students. The fully automated BGO, the spectrograph, and the BGO
spectrum reduction procedure are fully described in a companion paper. All
codes are available from the OpenStars www site: www.ap.smu.ca/OpenStars.
