SGP/EBBR/E13 - Invalid data during disconnection of AEM at E13

On December 31, 1993 at 1950 GMT the AEM on the Central Facility EBBR was
disconnected.  Another AEM was then connected, on which some testing was needed
before site operations could be confident that it was ready for field
installation at an extended facility.  At 2041 GMT the original AEM was
reconnected.  The following 5, 15, and 30 minute data between or for the stated
times below is invalid:

5 minute (1950 to 2045 GMT): tair_top, tair_bot, thum_top, thum_bot, hum_top,
          hum_bot, vp_top, vp_bot, home

15 minute (2000 to 2045 GMT): rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l,
           mv_home, tair_r, tair_l

30 minute (2000 through 2100 GMT): tair_top, tair_bot, thum_top, thum_bot,
           hum_top, hum_bot, vp_top, vp_bot, bowen, e, h, home_15, home_30
