SMART/SDDI Filament Disappearance Catalogue
This is the cataolgue of filament disappearance (or disparition brusque) observed by the SMART/SDDI (Ichimoto et al. 2017, SolPhys)

Footnote
- obs_date
- Local date of observation (JST)
- ar_location
- Active region location in Heliocentric coordinates. Unit is degree.
- ar_size
- Rough measurement of active region size. Unit is Mm^2.
- CME, central_PA, angular_width, linear_speed
- From The SOHO/LASCO CME Catalog
- credibility
- The credibility of CME–Filament disappearance association. 3 > 2 > 1. The events with a credibility of 1 might be controversial. For credibility NaN, the analysis has not yet been conducted, or there is no SOHO/LASCO C23 data. Note that its definition in ver201016 is different from the others.
- FD_start_time, FD_end_time
- When a filament disappearance started and ended.
- x, y
- The position of the center of a filament in arcsec.
- longitude, latitude
- The position of a filament center in the Heliographic coordinates. Unit is degree.
- Vx, Vy, Vz
- x-positive is to the solar west, y-positive is to the solar north, and z-positive is to the line-of-sight direction. Unit is km/s.
- Vr_max, Vr_fin
- The maximum and final radial velocities of the observed filament disappearance. "-" denotes that it was impossible to measure the velocity mostly due to the terrestrial cloud (see note). Unit is km/s.
- phi
- See Figure A below. Unit is degree.
- theta
- See Figure A below. Unit is degree.
- inclination
- See Figure B below. Unit is degree.
- length
- The length of a filament. Unit is Mm.
- Type
- Type of a filament or prominence. AF is an active region filament, IF is intermediate filament and QF is a quiescent filament.
- IPS_value & IPS_date
- Interplanetary Scintillations (Kakinuma et al. 1973, PASJ). For the definition of g-value, see Iju et al. 2013, SolPhys.
- ICME
- Interplanetary CME candidate from Richardson & Cane ICME Catalog.
- Dst_peak_value & Dst_peak_time
- The peak time value and time of Dst over the following 7 days after the end time of a filament eruption. These values are not necessarily associated with the filament disappearance. Users should be careful in considering the reasons for geomagnetic disturbance. Units are nT and UT, respectively.
