Dear Sudhir,
these terms refer to a MAD (multi-wavlength anomalous dispersion) experiment,
where you collect a data set each at different wavelengths from one crystal.
The actual wavlengths depend on the atom type you want to exploit in order to
carry out phasing, and they are usually determined from a fluorescence scan of
the particular crystal before the experiment is started.
In the presence of anomalous dispersion, such a scan shows a peak and an
inflection point at specific wavlengths. remote refers to either high energy
remote or low energy remote, depending on whether that data set is collected at
a wavlength below the peak wavelengths or above.
