184.108.40.206 Effective area for dispersive spectroscopy
Fig. 116 displays the effective area of both RGS units together (from Fig. 84), compared with different
Chandra instrument combinations. In order to avoid overcrowding the figure,
the combination of Chandra HRC+LETG is not shown.
The effective area of both RGS units combined,
compared with Chandra's ACIS-S instrument with
various transmission gratings. Note that since early
after the beginning of the mission, CCD7 in RGS1 and CCD4 in RGS2
are inoperative, thus the
effective area in each of the mentioned CCD energy range is
reduced by a factor of 2 (see Table 9).
