0.3 (March 2021)

  • now use DIT/NDIT instead of EXPTIME
  • prevent numerical overflow due to high background rates
  • updated notebooks (Geosnap for N-band, example using an image as a source)

0.2 (December 2018)

  • added LMS module, including an example notebook, configuration file and test data
  • adapted documentation

0.1 (October 2018)

  • first release of SimMETIS (based on SimCADO)
  • simulates all L,M and N band imaging modes of METIS (Q band may be supported later, if required)
  • background values and zeropoints have been compared to back-of-the-envelope calculations and the METIS fluxes document E-TNT-MPIA-MET-1004 (by Roy van Boekel)
  • the input data format can be any Source object that simcado understands (see documentation there), e.g. a point source, list of point sources, or an arbitrary FITS file
  • the output data format corresponds to a finally calibrated, background-subtracted, science-grade data product. It includes noise from the background and the object itself (photon shot noise) as well as from the background subtraction process. Detector read noise is not included as it is always less 10% of the background noise for reasonable DITs in all filters. Detector dark current is irrelevant for all bands.
  • emission from the entrance window (most relevant in the Q band) is not yet included. In the N band this causes a deviation of 10% from the expected value. This will be correctly implemented in a later version.
  • ELFN can be simulated in the N band by using the function that is supplied in the N band notebook.
  • Re-scaling the default PSF using scipy's zoom() function currently leads to a UserWarning that can be ignored.
