Comparative Analysis of Prominence Magnetic Field Measurements: Differences in Results Between Zeeman and Hanle Measurements

Results of magnetic field measurements in prominences using the Zeeman and Hanle methods are discussed critically. By considering an example of three prominences, for which magnetic field data from both methods are available, the discrepancies between the methods are demonstrated. The authors believe that the existing Hanle method does not reflect adequately the actual reality. To overcome the discrepancies calls for comparative analysis of prominence magnetic field measurements by both methods.
