They occur at a crucial time in the evolution of these systems, when the accretion disc emission starts to dominate over coronal emission. Flip-flops remain a poorly understood phenomenon, so we aim to thoroughly investigate them in a system featuring several such transitions. Methods: Within the multitude of observations of Swift J1658.2-4242 during its outburst in early 2018, we detected 15 flip-flops, enabling a detailed analysis of their individual properties and the differences between them. We present observations by XMM-Newton, NuSTAR, Astrosat, Swift, Insight-HXMT, INTEGRAL, and ATCA. We analysed their light curves, searched for periodicities, computed their PDSs, and fitted their X-ray spectra, to investigate the source behaviour during flip-flop transitions and how the interval featuring flip-flops differs from the rest of the outburst. Results: The flip-flops of Swift J1658.2-4242 are of an extreme variety, exhibiting flux differences of up to 77% within 100 s, which is much larger than what has been seen previously. We observed radical changes in the PDS simultaneous with the sharp flux variations, featuring transitions between the quasi-periodic oscillation types C and A, which have never been observed before. Changes in the PDS are delayed, but more rapid than changes in the light curve. Flip-flops occur in two intervals within the outburst, separated by about two weeks in which these phenomena were not seen. Transitions between the two flip-flop states occurred at random integer multiples of a fundamental period of 2.761 ks in the first interval and 2.61 ks in the second. Spectral analysis reveals the high and low flux flip-flop states to be very similar, but distinct from intervals lacking flip-flops. A change of the inner temperature of the accretion disc is responsible for most of the flux difference in the flip-flops. We also highlight the importance of correcting for the influence of the dust scattering halo on the X-ray spectra.   Improved shallow water demultiple method with multichannel prediction operators 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2019, 卷号: 62, 期号: 2, 页码: 667-679 作者:  Zhou XiaoPeng;  Liu YiKe;  Li Peng   |  收藏  |  浏览/下载：33/0  |  提交时间：2019/03/21 Shallow water  Multiple suppression  Water-layer related multiples  Adaptive subtraction   Migration of seismic multiple reflections 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2018, 卷号: 61, 期号: 3, 页码: 1025-1037 作者:  Liu YiKe;  Liu XueJian;  Zhang YanBao   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/09/26 Surface-related multiples  Internal multiples  Controlled-order  LSRTM   Strategy of multiple elimination by sparsity inversion and its effectiveness analysis 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2017, 卷号: 60, 期号: 12, 页码: 4801-4813 作者:     |  收藏  |  浏览/下载：21/0  |  提交时间：2018/09/26 Sparsity Inversion  Primaries  Surface-related Multiples  Multiple Attenuation   Strategy of multiple elimination by sparsity inversion and its effectiveness analysis 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2017, 卷号: 60, 期号: 12, 页码: 4801-4813 作者:  Bai Lan-Shu;  Liu Yi-Ke;  Lu Hui-Yi   |  收藏  |  浏览/下载：21/0  |  提交时间：2018/09/26 Sparsity Inversion  Primaries  Surface-related Multiples  Multiple Attenuation   Eliminating migration artifacts in angle domain based on one-way wave equation migration of multiples 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2016, 卷号: 59, 期号: 12, 页码: 4584-4593 作者:  Zheng, Yi-Kang;  Wang, Yi-Bo;  Chang, Xu;  Yao, Zhen-Xing   |  收藏  |  浏览/下载：40/0  |  提交时间：2017/11/20 High-resolution Radon Transform  Angle Domain Common Image Gathers  Migration Artifacts Of Multiples  Data To Data Migration   Least-squares reverse-time migration of surface-related multiples 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2016, 卷号: 59, 期号: 9, 页码: 3354-3365 作者:  Liu Xue-Jian;  Liu Yi-Ke   |  收藏  |  浏览/下载：22/0  |  提交时间：2017/11/21 Least-Squares Reverse-Time Migration (LSRTM)  Migration of multiples  First-order multiples
