Version 14.0 of the Science Analysis System (SAS) released

• An energy-dependent correction to the CTI is now applied, and the time dependency has been updated, to represent better the observed time evolution (http://xmm2.esac.esa.int/docshttps://www.cosmos.esa.int/documents/CAL-SRN-0323-1-0.ps.gz).
• The dependency of the spectral energy resolution on time and pattern has been introduced. This change implies that EPIC-pn response matrices are now time dependent (http://xmm2.esac.esa.int/docshttps://www.cosmos.esa.int/documents/CAL-SRN-0322-1-0.ps.gz).
• Changes improving the accuracy of the energy scale in the fast modes have been included, that apply differently to the different modes. To make their use easier, the new parameter withdefaultcal (with default yes) has been introduced in both epproc and epchain. Also, the systematic offset in the energy scale of single- and double-event spectra is now corrected by epevents (http://xmm2.esac.esa.int/docshttps://www.cosmos.esa.int/documents/CAL-SRN-0323-1-0.ps.gz).
• A new task for soft flares flagging, eprejectti, replaces epreject for EPIC-pn Timing mode data.

• An empirical correction to improve the cross-calibration of the EPIC effective areas has been introduced as a new option in arfgen. Since the calibration is still preliminary, currently its use is only recommended as a tool to estimate the impact of effective are inter-calibration uncertainties. It can be used through the non-default parameter applyxcaladjustment (http://xmm2.esac.esa.int/docshttps://www.cosmos.esa.int/documents/CAL-SRN-0321-1-1.pdf).
• The new metatask eimagecombine produces combined smoothed, background-subtracted and exposure corrected EPIC images. This task uses as input the individual sets of images from the, also new, task eimageget.

• The heliocentric and solar aspect angle corrections to the wavelength scale are applied by default.

• A general upgrade of many tasks has taken place, corresponding to the developments leading to the OM catalogue.
• The OM SAS interactive tasks for manipulation of source lists, omsource and omgsource, run now flawless in the 64-bit SAS versions.
• omfchain processing of OM fast mode data now extracts correctly the background from the associated image.
