Scientific paper

We have developed a new code for measuring stellar magnetic fields by calculation using fast transforms of the Fourier cross-correlation function from spectra with reciprocal circular polarization. To test the code, spectra of stars with previously measured magnetic fields were used. In some cases, discrepancies between the field strength obtained by Babcock's classical technique and using our code occur.
