HEEPS is a high-contrast imaging (HCI) simulator, mostly geared towards studying the HCI performance of the ELT/METIS thermal infrared instrument.

Currently, the simulator includes four coronagraphs:

• Classical Vortex Coronagraph (CVC)
• Ring Apodized Vortex Coronagraph (RAVC)
• Apodizing phase plate (APP)
• Classical Lyot Coronagraph (CLC)

Dependencies

HEEPS depends on existing packages from the Python ecosystem, such as numpy, scipy, matplotlib, astropy, photutils, skimage. It also relies on more specific package: VIP for HCI image processing and PROPER for optical propagation
