v3.2.0

EXOSIMS v3.2.0

This release updates and fixes functionality associated with common exosystem inclinations, improves computational efficiency in the Nemati OpticalSystem implementation, and fixes a bug associated with the new (in v3.1.0) stellar flux calculations.

New Functionality

Previously, EXOSIMS could generate planets about the same target star with the same inclination via the commonSystemInclination and keyword, and setting commonSystemInclinationParams, which described the mean and standard deviation of a normal distribution of offsets from the common system inclination. However, the longitude of the ascending node of these planets would still be sampled independently, meaning that the planets, while having the same inclination, would still lie in different orbital planes. With this release, the commonSystemInclination inputs are deprecated and replaced with commonSystemPlane and commonSystemPlaneParams, which toggle on the common system plane and set the parameters of offset distributions for both inclination and longitude of the ascending node. Internally, when this functionality is toggled, the TargetList now generates both a system mean inclination and longitude of the ascending node, thereby defining a true common system orbital plane.

Performance Improvements

The converged Boolean in the OpticalSystem.Nemati.calc_dMag_per_intTime function has been moved out of the lower bound loop to avoid always running the minimization twice.

Bug Fixes

Two issues previously existed associated with the case when a star is evaluated to have zero flux in the observing band. First, this leads to a synphot error, which is now suppressed. Second, this leads to a calc_dMag_per_intTime inversion error - this is now handled by filtering out all stars with zero flux in the observing band prior to any downstream calculations (in TargetList.calc_saturation_and_intCutoff_vals).
