Description

The C++ pointing accelerations currently focus on projections that represent the brightness of the sky, as sampled by multiple detectors. But as identified and implemented by @yoshinori-0778 in sotodlib, an important complementary approach is to represent the response of each detector as a function of position relative to that detector. One can stack such response functions, for many detectors, aligning them all either so that the polarimeter principle axes align ("detector centered") or preserving some relative orientation between the detectors ("instrument centered").

Research direction

Start by locating the C++ pointing accelerations and reviewing the corresponding implementation in sotodlib. Compare detector-centered and instrument-centered response projections, including how detector positions and polarimeter axes are aligned. Done means both projection approaches are supported for stacked detector response functions.
