Tools and Tips

VISIR Papers

Publications based on data obtained with the VISIR instrument should quote the following reference paper: Lagage, P.O. et al. 2004, The Messenger 117, 12.

A description of the VISIR upgrade can be found in Käufl, H.U, et al., 2015, The Messenger 159, 15.

GuideCam Software

  • This tool (GuideCam) is used to select the guide star and prepare the finding charts in the proper format.

VISIR-specific tools

The most commonly used calibration sources in the mid-infrared are the ones characterised by Cohen et al. in a series of papers starting in 1992: "Spectral Irradiance Calibration in the Infrared". A summary of these papers including a spectro-photometric catalogue of 422 stars scattered over the entire sky can be found on their Paper X (Cohen et al. 1999, AJ 117, 1864). This catalogue is included in the VISIR pipeline and the basis of the sensitivity determination for VISIR. Nevertheless these templates should be used with caution, because many of them have not been verified observationally.
