Assessment
This issue has not been assessed yet.
Description
This is a common operation that could easily be encapsulated in a general way:
from so3g.proj import quat
fp = aman.focal_plane
bs = aman.boresight
qbs = quat.rotation_lonlat(0, bs.el[0], bs.roll[0])
qdets = qbs * quat.rotation_xieta(fp.xi, fp.eta)
az_det, el_det, _ = quat.decompose_lonlat(qdets)
az_det = -az_det
