Editing Markers/Endpoints

Editing markers and endpoints works much the same, regardless of the type of acquisition data being analyzed.

For surveys, AES and SIMS markers can be placed on survey data by tracing the markers, and XPS endpoint markers can be placed on a survey data by selecting endpoints.

For survey data peaks can also be identified by loading markers from a list. Individual markers can be removed from the list. Also, markers can be flagged as to their use for atomic concentration calculations. Note that by default, Argon is excluded from this list.

Additionally, endpoints can be placed on the individual regions of an AES or XPS mulitplex and profile. In the case of AES, the endpoints define the upper and lower analysis limits for atomic concentration calculations. For XPS, the endpoints define the baseline of the region

Surveys:

Saving a Marker/Endpoint List

To save a marker list for future use, first select a survey that has the peaks of interest marked. For AES and SIMS surveys, choose the Markers command from the Edit menu (for XPS surveys, choose the Endpoints command from the Edit menu). The Edit/Remove Markers dialog will appear. You can now remove individual markers or change the marker state before saving. Choose the Save button when the marker list is ready. Marker files will have a ".mls" extension by default.

Loading a Marker/Endpoint List

To load a marker list, select the survey to mark. For AES and SIMS, select Markers from the Edit menu (for XPS surveys, choose the Endpoints command from the Edit menu). The Edit Remove Markers dialog will appear. Click the Load button, and browse to the marker file of interest (marker files have a ".mls" extension by default). Note that any markers in the file that fall outside the eV range of the survey will automatically not be included.

Flagging Markers/Endpoints for Atomic Concentration

By default, when markers are entered they are flagged to be included for atomic concentration. To select or deselect a marker, select the survey of interest and choose Markers from the Edit menu for AES or SIMS (for XPS, select Endpoints from the Edit menu). The Edit/Remove markers dialog will appear. Click the checkbox next to the marker of interest. Checked markers are used in the Atomic Concentration calculation, unchecked markers are not. Note that all markers still appear on a survey.

For survey, multiplex and depth profile data:

Removing Markers/Endpoints

To remove all markers or an individual marker from a survey, select the survey of interest, then choose the Markers command from the Edit menu for AES or SIMS (for XPS, select Endpoints from the Edit menu). To remove all the markers, click the Remove All button. To remove an individual marker, select the marker and click the Remove button.
