Single shell model of a true Wolter Type I optic

Identification

• Site: AstroX_ESA
• Author: Erik B Knudsen & Desiree D. M. Ferreira (email)
• Origin: DTU Physics/DTU Space
• Date: 12/12/2016

Description

Single shell example telescope using a combinatiopn of parabolic/hyperbolic shell
optical plates covering the full circle. Reflectivity is 1 for all energies.

Example: Test_shells.instr shell_type=1

Examples

(Test cases in bold)

• Test: shell_type=0 Detector: detector_post_optics_I=0.036946
• Test: shell_type=1 Detector: detector_post_optics_I=0.036946
• Test: shell_type=2 Detector: detector_post_optics_I=0.036946

Input parameters

Parameters in boldface are required; the others are optional.
