Applying Wavelength Corrections to HRC-S/LETG Data

corrlam provides empirically-derived corrections to photon wavelengths in level 1.5 and level 2.0 event lists to ameliorate HRC-S event position errors. These dispersion relation corrections are discussed in a previous memo and SPIE publication. You may download version 1.0, or read the usage information. corrlam is written in Perl and requires both the PDL and Astro::FITS::CFITSIO modules, which can be found on a local CPAN mirror.
