theta and phi value in *.npz generated by Kite(both for scripy and spool GUI) based on ROI_PAC results are only values not a ndarray. But in "beat import $project_dir" command, theta and phi must be an ndarray( see quadtree.py in Kite module).
From the scene.py and scene_io.py, theta value is always a value not a ndarray for ROI_PAC results.
In Class ROI_PAC (scene_io.py)
c.theta = num.deg2rad(90. - look)
look = num.mean(num.array([look_ref1, look_ref2, look_ref3, look_ref4]))
c.phi = num.deg2rad(-heading + 180.)
heading = par['HEADING_DEG']
