3.4.4.8.2 Pile-up mitigation

The effects of pile-up can be mitigated by reducing the accumulation time. The main methods to achieve this are reading fewer CCDs, reading the most brightly illuminated CCDs more often or using the RGS Small Window mode, or even a combination of these. The XMM-SOC document XMM-SOC-CAL-TN-0075, available from http://xmm2.esac.esa.int/docs/documents/, gives more details about pile-up in RGS.
