Reflect is software to analyze seismograms containing reflected arrivals gathered from a single shot.
Reflect uses five different windows: the Model Window, the Plot Window, the Data Window, the Fit Window, and the Section Window. Many of these windows share the same basic menu items. Some aspects of Reflect are set in the Preferences Window.
A typical use of Reflect is to try to find a seismic velocity structure that will reproduce observed reflection arrivals. It can also be used to predict arrival times for suspected structures prior to acquiring data, as when identifying a good offset for a fixed-offset reflection survey.
Users would usually start in the Model Window, specifying the geometry of the geophones and shot and the number of layers in the model. The waves to be shown are selected in the Model Window. Opening the Plot Window will show seismograms with the arrivals specified in the Model Window. Picks made from a reflection gather can be entered by opening the Data Window, which also shows the predicted arrival times for the selected waves. These data can be inverted by launching the Fit Window, which allows the user to fit lines to the picks on a t^2 versus x^2 plot. These lines can then be run from the Model Window through the Dix equation to recover estimates for the velocity structure. The structure can also be edited in the Model Window to try and fit the data.
