Pixel inverse condition numbers for the HWP setups under consideration. First column: HWP stepped every 1 s (solid black line), 60 s (dotted red line) and 3600 s (dashed blue line), for a telescope scanning at 12 deg/s (top) and 0.7 deg/s (bottom). Second column: HWP spinning at 5 Hz (solid black line), 2 Hz (dotted red line) and 0.5 Hz dashed blue line), for a telescope scanning at 12 deg/s (top) and 0.7 deg/s (bottom). In our convention, the condition number Rcond has a value running from 0 to 0.5, where Rcond = 0.5 means perfect angle coverage.
