LETG: Low Energy Transmission Grating

The Low Energy Transmission Grating on Chandra (PI: A. Brinkman, SRON, Utrecht, with the collaboration of MPE, Garching) provides a spectral resolution of about 1000 in the 0.05-2 keV band (6-150 Angstrom). The dispersed spectrum is normally read out by the HRC-S.
