SPEARHEAD Forbush decreases catalogue

Forbush decrease catalogue (FDcat) of measured flux-rope related Forbush decreases in Helios, Solar Orbiter, Ulysses, SOHO, South Pole neutron monitor and MSL/RAD. Each line, i.e. entry, in the catalog represents a single unique measurement/fit that was performed. Thus, for a single event there may be multiple entries. The description of the columns (values separated by tab character) is as follows: id: unique identifier for each entry in all the catalogs consisting of connected strings holding information on observer, instrument, timing and border type: FD_{SATELLITE}_{GCR_DETECTOR}_{OBSERVER_NAME}_{DATE}_{BORDER_TYPE} year: year of the start of the event date: date of the start of the event in the form yyyy_mm_dd or dd.mm.yyyy in situ s/c: satellite performing in situ measurements GCR detector: detector performing GCR measurements dist [AU]: heliocentric distance at which the measurements were performed in au clong: carrington longitude at which the measurements were performed in degrees clat: carrington latitude at which the measurements were performed in degrees borders: type of the border selection as described in Section 4.1 (extended, inner, optimal), where it is also possible to have ’test’ for events that the observer wants to highlight or not include in the analysis DOY Start: the start time of the event, i.e. day-of-year (DOY) corresponding to the starting border of the measurement/fit DOY End: the end time of the event, i.e. day-of-year (DOY) corresponding to the ending border of the measurement/fit DOY FDmin: day-of-year (DOY) corresponding to the minimum of FD with respect to the onset (starting border) vAvg [km/s]: average plasma flow speed in the interval between selected borders vMedian: median plasma flow speed in the interval between selected borders vStdev standard deviation of plasma flow speed in the interval between selected borders vLead: plasma flow speed at the leading edge, i.e. at the start time v_center: plasma flow speed in the center of the interval between selected borders vTrail: plasma flow speed at the trailing edge, i.e. at the end time upstream_w: ’quiet solar wind’ plasma flow speed upstream of ICME arrival, calculated as average in the interval selected by the observer BPeak [nT]: Maximum total magnetic field measured in the interval between selected borders BAvg: average total magnetic field in the interval between selected borders, in nT BMedian: median total magnetic field in the interval between selected borders, in nT BStdev: standard deviation of total magnetic field in the interval between selected borders, in nT FD_obs [%]: FD amplitude measured from the onset to the minimum of FD (i.e. using standard FD amplitude determination) FD_bestfit: FD amplitude determined based on ForbMod best-fit MSE: mean square error of the fit, i.e. goodnes-of-fit fit type: observers characterisation of the fit based on visual inspection (good, asymmetric, few-data-points, large scatter, under-recovery, substructuring) notes: any notes given by the observer (typically contains information whether event is present in some of the catalogs and where) QI: quality index, based on observers remark on data gaps, interactions, small magnetic flux ropes (SMFR) lack of depression or GCR increase [1-no comment, well defined single event; 2-interaction reported (CME or HSS or both); 3-bad fit/data gap reported; 4-smfr; 5-exotic event (e.g. GCR increase; strange offset or clearly MO but no FD, or shock-sheath only)
