Hi Andy,

Yes – happy for you to use whatever you want.  My reason for earlier question about normalisation of spectra was that I took sets of images in between the dates given in the figure.  Haven’t processed all of them yet, but had it in mind to see if I could put some numbers to any changes by measuring equivalent widths if possible [Richard Walker document explains how to do this and Rspec has facility to do the measurements – not sure how accurate though – would be first try out of it].
