Table 13.42: Spectral Resolution for Echelle Medium-Resolution Modes (E230M, E140M)
FWHM with FUV-MAMA (E140M).
FWHM with NUV-MAMA (E230M).

FWHM with NUV-MAMA (E230H).
Figure 13.92: Echelle Line Spread Functions, E140H (top) and E230H (bottom). LSFs for E230H were derived using the 0.1X0.2 and 0.1X0.09 apertures, but results for 0.2X0.2 and 0.2X0.09 should be similar.
