GEOTAIL Regime ID Abbreviations

 Abbr  Description
 ----- -----------------------------------------------------------------------
 BL   Boundary Layer: mantle here; high B(>5g), +Bx(>4g), low dB, no EM waves
 BS   Bow Shock: [similar to SW]
 Cal   Calibration period
 d(cs) distance to current sheet
 FF    Fast Flow event [similar to PS]
 FL    Flare, used when there is some flare background
 FR    Flow Reversal
 LB   Lobe: mostly < 1 keV ions
 MG    Magnetosphere: ions > 1-5 keV, 1-10 keV electrons (e-) [similar to PS]
 MS   Magnetosheath: low B (<5g), -Bx, high dB, EM waves, 1+ keV ions
 PS   Plasma Sheet: 100 eV+ ions, < ~1 keV electrons (e-)
 RF    Reduced Flow (sec p. 3)
 Rot   B rotation without boundary in plasma
 RTO   Repeated Transient Observations
 Sat   "saturated" plasma instrument readout(s); data was difficult to interpret
 SW   Solar Wind
 Gap   No ID available due to a Gap in the data record
 ?     Unknown
 No_ID No ID characterizes the period
