Summary of the calibration of the apertures sizes in the BKG detector of STIX.
| Ratio | Pixel | Nominal | Optical | In-flight |

Notes. The top part of the table gives the results for the ratios we got from the analysis described in Section 3.2. The lower part of the table summarizes the sizes of the apertures as determined in Sections 3.1 and 3.3. For each pixel (or ratio), we report the nominal value, the optical and the in-flight measurement.
