Hi, is there a way to resample a spectra (even twodimensional or monodimensional) in natural logarithm, instead of decimal logarithm??

Hi,
The only choice provided is decimal log. Because decimal and natural logs are simply related by a scale I don't see that the distinction is important. You could always use HEDIT to change the header keywords that define the decimal log WCS (things like CRVAL and CD). Note this would probably make onedspec tasks like SPLOT produce funny axes.
