Abstract
The performance of the second version of the Manchester Echelle spectrometer is described when combined with the San Pedro Martir, 2.1 m telescope. The simplicity but effectiveness of the optical design is explained as a consequence of the spectrometer's dedication to a narrow range of astrophysical problems i.e., where spatially resolved line profiles are required from faint, extended sources at high signal-to-noise ratios. The improvement in operational efficiency is demonstrated as a consequence of the recent (2000) upgrade of the control system. Finally, comparisons are made with the performance of competitive stepped Fabry-Perot interferometers on similar problems. The complementarity of spectrometers of different types is emphasized.Similar Articles
