HDS Exposure Time CalculatorNote1: Use HDS Echelle Format Simulator to check the detailed spectrum format with the desired instrument setting. Note2: Since the template spectra cover a limited wavelength range, correct normalization of the spectrum may not be possible at high redshift. Note3: The efficiency of Image Slicer is compared with the normal slit (0.3 (for IS#1), 0.45 (for IS#2), or 0.2 (for IS#3) slit width) observation. If this value is presented in red, the order gap might be too small. Akito Tajitsu, 16 February 2018 |
