SDO/AIA 193 Å intensity filtergram (top), ALMA Band 6 brightness temperature (T_b) image (middle) and SDO/HMI magnetogram (bottom) of full solar disk (left) with zoomed region around CH2 (right), both containing extracted boundary of CH2 (red – AIA, HMI, cyan – ALMA), obtained with CATCH using SDO/AIA 193 Å image. The selected CBPs are marked with circles (white – within CH2, yellow – outside CH2), where the radius of each circle equals half of the maximum length of a CBP multiplied by a factor of 1.7. The SDO/AIA intensity is clipped between 20 and 6000 DN, ALMA brightness temperature between 5500 and 7000 K, and SDO/HMI magnetic field between −120 and 120 G. Similar figures for CH1, CH3, CH4 and CH5 are given in Appendix B.
