Porting code from HSC to LSST brought over a unit test into meas_algorithms for functionality that exists in meas_base in LSST. This is due to the refactoring of code into meas_base on the LSST some while ago. This unit test currently runs with code from meas_algorithms, which means it can not simply be moved, as meas_base comes before meas_algorithms in the build order. This work may involve rewriting the unit test to use different code, or evaluating if it is worth bringing that functionality to meas_base along with the test. The code in question is the detection task.
