Instructions

This table contains several interactive features:

• Pass the mouse over a Package Name box and the corresponding SAS tasks that are needed to complete the given package will be highlighted in gold.
• Pass the mouse over a group of SAS tasks and those SAS tasks which are mandatory to be run beforehand will be highlighted in red, and those that are optional will be marked in green.
• If a thread, or section of a thread, is available describing how to perform a specific task, or a set of tasks, it will be marked by in the Thread column. Placing the mouse over , the name of the corresponding thread is shown in a pop-up window.

Note: for a best view of the full table, use CTRL + '+' and CTRL + '-' to increase or reduce the zoom until the table fits in the whole browser window.

Go to Data Processing Go to Calibration	Package Name	Comment	SAS Tasks	Thread
DATA ANALYSIS Scientific product extraction	Point Source Extractor Metatask for data processing	pn, MOS, RGS, OM Extract scientific reduced data related to point sources, starting at the ODF level, corresponding to a given observation. It allows for some analysis interactivity to be carried out	xmmextractor
	Optimize Extraction Regions Optimize point-like source extraction regions	pn, MOS Optimize source and background extraction regions for further data processing like the creation of images, light curves and spectra	evselect+ eregionanalyse , or especget

		OM Create OM light curves (fast mode)	omfchain
	Source Detection Run source detection algorithms over EPIC and OM observations	pn, MOS Run source detection algorithms on EPIC calibrated and filtered images to produce a list of the sources detected in an observation. It is also possible to run source detection tasks on a set of overlapping EPIC observations	edetect_chain emosaic_prep+ emosaicproc (for source detection in overlapping fields)
		OM Interactively create, or modify, a list of the sources detected in a OM observation. It also performs upon images produced by ommosaic	omsource
	Slew Processing Process slew data taken with the pn camera	pn Produce filtered event files and images for pn data taken during slews	eslewchain
	Extended Sources Process data from extended sources	pn, MOS Extract a radial profile of a source in an image and fit a point spread function to it to test whether a source is extended	eradial
		pn, MOS The ESAS package includes tasks to create source and model particle background spectra and exposure-corrected, background-subtracted (particle and soft proton) images. It also offers software for mosaicking multiple observations of not necessarily co-aligned observations. More information about the analysis of extended sources in EPIC can be found at the BGWG pages. An ESAS warnings and watchouts page is available from NASA XMM-GOF.	mos-filter pn-filter cheese make_mask region mos-spectra mos_back pn-spectra pn_back proton rot-im-det-sky sp-partial comb adapt_900 adapt_2000 bin_image
