Since the output from pass-through measurement is inevitably smoothed and distorted by the response function of the sensors, deconvolution of the measurement result is necessary to obtain accurate signals of the sediment. Methods of deconvolution have been improved by modeling the remanent magnetization as a smoothly changing function by minimizing Akaike's Bayesian information criterion. In this study, we developed deconvolution programs for pass-through magnetic susceptibility data based on the same algorithm, first by using a single smoothness parameter for the entire sample and then introducing an additional parameter for the interval with a strong susceptibility peak. Applying these programs to U-channel samples from Lake Tazawa, Akita Prefecture, it was confirmed that results of the deconvolution well correspond with susceptibility of the discrete samples. However, the interval with a sharp susceptibility peak produced noisy erroneous variation, suggesting that further improvement is necessary for deconvolution of the samples including tephra or event layers.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2019.0000000071","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
