SAS Inverse Index
Data Processing

Instructions

• 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.

Go to Data Analysis Go to Calibration	Package Name	Comment	SAS Tasks	Thread
DATA PROCESSING Prepare data for scientific product extraction	Data Preparation Compile ODF information	All instruments Construct an index of the calibration files required to analyze a particular Observation Data File (ODF). Also, it is necessary to create an ODF summary file by combining information from the observation itself with that extracted from the instrument housekeeping datasets	cifbuild odfingest
	Calibrated Event Lists Obtain calibrated event lists for all instruments	pn Process the pn part of an ODF in order to obtain a calibrated event list	epproc , or epchain
		MOS Process the MOS part of an ODF in order to obtain a calibrated event list	emproc , or emchain
		RGS Process the RGS part of an ODF in order to obtain a calibrated event list	rgsproc
	Event List Filtering and Diagnostics Prepare calibrated event lists for scientific product extraction	pn, MOS Filter an event list for periods of high background flaring activity. Define and create Good-Time-Intervals (GTI). Several methods are available to create GTIs	evselect + tabgtigen , or espfilt
		RGS Filter an event list for periods of high background flaring activity. Define and create Good-Time-Intervals (GTI)	evselect+ tabgtigen
		RGS Remove unwanted frames and events from the combined event list for RGS	rgsfilter
		pn Evaluate and correct images and spectra for Out-of-Time (OoT) events	evselect
		pn, MOS Assess whether an observation is affected by pile-up	epatplot
		RGS Assess whether an observation is affected by pile-up	rgsfluxer
		MOS Check and flag MOS CCDs affected by enhanced electronic soft X-ray noise present in some observations	emtaglenoise
	Photometry and Spectroscopy Obtain images, source lists, light curves or spectra	OM Process the OM part of an ODF in order to obtain images and source lists, light curves or spectra	omichain (image data) omfchain (fast-mode data) omgchain (grism data)
