Confidence levels for events are a new feature for v2.1. You will be more sure about the position of some events than of others. A strong flood of specimens makes a more definite marker than a single, poorly preserved top. Can you be sure you have located the relevant abundance peak? If you are going to base other interpretations on event picks (especially a depth\/age curve), then you will want to give yourself some guidance as to the reliability of those picks. Here I will demonstrate the ways you can apply confidence to events in order to give yourself this support.<\/p>\n

Events in wells<\/h3>\n

To change the confidence level for a well event, select from the drop-down in the Event dialog:<\/p>\n

\"well-event-dialog\"<\/p>\n

You can set the events panel to display less confident events in a lighter colour.<\/p>\n

\"event-panel\"
Note that you must also select “use colours”.<\/figcaption><\/figure>\n

Don’t forget that you can display events on your taxon distribution chart (for example, download the “Event Age” panel template from here<\/a>). This is handy for deciding on the confidence level – you can easily spot the more dubious events and designate them accordingly. You can double-click on an event to edit it. In this panel, the colour changes where the event is picked. The colour change is more pronounced where the event is more confident.<\/p>\n

\"well-event-panel\"
The left-hand track, showing the “possible” SA event, shows a less prominent colour change than the right-hand track which shows the “confident” C event.<\/figcaption><\/figure>\n

Events in time (composite standard events)<\/h3>\n

Composite standard events are configured and displayed in much the same way. The stratigraphic range panel shows ‘probable’ events with a dashed line and ‘possible’ events as a dotted line.<\/p>\n

\"cmp-std-range-panel\"<\/p>\n

\u00a0Cross-plot of events (depth\/age chart)<\/h3>\n

On a depth\/age chart, confidence levels of both types of event help you when placing your curve. Events are shown with a lighter-weight line when their age is less confident, and a lighter colour when their depth is less confident.<\/p>\n

\"depth-age\"
(1) Probable FAD \/ Probable LDO; (2) Possible LAD, Confident FDO; (3) Confident LAD, Possible LDO.<\/figcaption><\/figure>\n

Note that the confidence is subjective: it’s not based on data from adjacent samples. The event depth range “tails” are based on the next analysis within the discipline under the assumption that, for instance, a top event could extend right up until the next sample, and vice versa for a base.<\/p>\n","protected":false},"excerpt":{"rendered":"
