Issue Date: | 2018 | Volume: | Ground-based and Airborne Instrumentation for Astronomy VII | Editors: | Evans, Christopher J. ; Simard, Luc ; Takami, Hideki | Series: | PROCEEDINGS OF SPIE | Number: | 10702 | First Page: | 107029I | Abstract: | We present an application of the HIRES End-to-End (E2E) simulator and HIRES Exposure Time Calculator (ETC) to derive a more detailed behavior of the spectrograph efficiency by including physical modeling of diffraction at the echelle grating and the cross-disperser. The result will be used with the Spectral Energy Distributions of calibration lights for wavelength solutions and flat fielding to quantitatively characterize the spectrograph in terms of achieved accuracy. By showing the contribution of photon noise, detector noise and cross talk between adjacent fibers we discuss methods that could be used to determine the overall performance of the instrument, in term of the capability of photon collection as well as especially on the achieved precision on wavelength calibration that translates directly in radial velocity accuracy of the scientific light. | Conference Name: | Ground-based and Airborne Instrumentation for Astronomy VII | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/30620 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/107029I/ELT-HIRES-the-high-resolution-spectrograph-for-the-ELT/10.1117/12.2313360.full | ISSN: | 0277-786X | ISBN: | 9781510619579 9781510619586 |
