Octofitter is a Julia package for performing Bayesian inference against direct images of exoplanets, relative astrometry, and astrometric acceleration of the host star.
The HGCA includes the covariance between parameters for each target. This should be incorporated into the PropMotionAnomHGCA likelihood function instead of treating RV and DEC proper motion as independent.
