+===== PBS Energy Layers =====
+Below is a list of some common functions that are helpful to compute appropriate machine deliverable energy layers and settings for PBS beams and a brief explanation of their intended usage (Specific details of each function, argument parameters, and return values are provided at the [[http://docs.apps.dotdecimal.com|Dosimetry App Manifest Guide]]).
+  * **compute_range_extents_from_structure_geometry:**
+    * Computes the minimum and maximum radiological path length necessary to reach the provided target for the a proton beam
+  * **create_pbs_layer_list:**
+    * Creates a vector of machine deliverable energy layers (that contain no spots) that cover the specified range extents and are spaced according to the specified spacing strategy
+  * **create_pbs_layers_for_target:**
+    * Computes a list of deliverable layers and spots that will fill the given target structure plus the nearby area as specified by the given margins and spot & layer spacing strategies
+  * **create_pbs_layers_from_spots:**
+    * Converts a list of spots to deliverable calculation layers according to the provided machine definition; an error will be thrown if the provided spot list contains undeliverable spot energies
