Detailed description of the suggested HDOR-RIM dosimetry formalism and measurements needed to obtain the jig factor and off-axis ratio. This along with Equations 1 through 9 and the following notation will allow the user to perform any necessary dose calculations for this protocol. ${\dot{D}}_C^W$: Dose rate to water measured in air at isocenter point C without irradiation jig present. D_M: Dose to water in phantom at position M. D_H: Dose to water in phantom at position H. D_B: Dose to water in phantom at position B. ${}^{\mathit{\text{ph}}}R_M^H$: Dose ratio between point H and point M in phantom. ${}^{\mathit{\text{ph}}}R_M^B$. JF_center: Jig Factor, measured at isocenter with Gafchromic film comparing the dose with or without the jig.
