The thin client at http://cdaweb.gsfc.nasa.gov/cgi-bin/eval3.cgi has in its source code, the following reference:

cgi-bin/eval3.cgi?dataset=+RBSP-A-RBSPICE_LEV-2_TOFXEION+RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3
   &events=2005%2F09%2F07+00%3A00%3A00%092005%2F09%2F20+00%3A00%3A00

   &var=RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3+Mag
   &var=RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3+coordinates

This was from a requested plot having two sources (RBSP-A-RBSPICE_LEV-2_TOFXEION and RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3).  The sources:
  RBSP-A-RBSPICE_LEV-2_TOFXEION             FIDU
  RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3    Mag
  RBSP-A_MAGNETOMETER_4SEC-SM_EMFISIS-L3    coordinates

And the timerange here is 
  start=2014%2F02%2F28+18%3A00%3A00.000
  stop=2014%2F03%2F01+18%3A00%3A00.000
which when expressed as ISO8601 range is:
  2014-02-28T18:00:00.000/2014-03-01T18:00:00.000

This is expressed as a minimal vap:
