A buffer zone of 0.25 angstrom in template browser may introduce line templates which are not present in the data cube

[yjzhu-solar]

It is convenient to check and select available lines through the eis_browse_template GUI. However, sometimes a buffer of 0.25 angstrom in the maximum and minimum wavelengths may introduce additional lines not included in the dataset. For example, in eis_20071112_011726.head.h5, window 15 has a wvl_max = 264.10, but the template browser still includes the S X 264.23 line in the available templates. Is it a good idea to downsize this buffer zone?
