Context: Instrumental profile (IP) is the basic property of a spectrograph. Accurate IP characterisation is the prerequisite of accurate wavelength solution. It also facilitates new spectral acquisition methods such as the forward modeling and deconvolution. Aims: We investigate an IP modeling method for the fibre-fed echelle spectrograph with the emission lines of the ThAr lamp, and explore the method to evaluate the accuracy of IP characterisation. Methods: The backbone-residual (BR) model is…

A crucial test for astronomical spectrograph calibration with frequency combs

Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy 1 – 6 . This development is considered key in the hunt

Report on the ''2017 ESO Calibration Workshop: The Second-Generation VLT Instruments and Friends''

The participants — from ESO Headquarters in Garching and from the Chile sites, from various institutes in Europe, from Gemini Observatory, Las Campanas Observatory, the Large Synoptic Survey Telescope project, US National Institute of Standards and Technology (NIST), the Pontificia Universidad Catolica de Chile (PUC), the Center for Astronomy in Harvard, USA — listened to presentations grouped in sessions organised around a central theme.
