| 3 | 4 | This data set consisted of two exposures taken with the default voltages, one with the microtest 05 voltages (SW_L = default - 1.0 V, SW_H = default - 1.0 V), and six others that vary only SW_L or SW_H (with the other set to the default value). To study the impact of these changes, I reduced the data as before, and found the best fit lines in the dx and dy offsets as a function of instrumental magnitudes. The data were binned using 0.1 magnitude bins, and the fit performed between -14 and -12 (other fits were performed using ranges (-16:-14) and (-12:-10), but are not shown here). |
