The wavelength correction can be found using {{eis_wave_corr_hk.pro}}, the {{gethkwavecorr()}} method of the eis_data object or eis_prep.pro. All procedures use specially prepared house keeping data files that are distributed with SolarSoft in the directory {{$EIS_DATA/wave_corr}}. If the house keeping files that are needed for correcting a certain EIS raster are missing in your SolarSoft installation, the new routines will search for the files in {{$EIS_WAVE_CORR_HK_DATA}} (if this environment variable is set), and in the current working directory. If the files are not found, or if newer versions of the files exist in the Oslo archive, they will automatically be downloaded and saved in {{$EIS_WAVE_CORR_HK_DATA}} (if set) or to the current working directory (if not set). Note that the house keeping files for a specific month are updated every night on the Oslo servers until the month is passed, i.e. if you work with observations from the current month new house keeping files will be downloaded to your machine every day until the end of the month.
