 3. Alerts 
 =========

 3.1 All alerts except OOLs and missing scientific data

   * Level 2:

2002 At least one HK (configuration) parameter changed unexpectedly
     Program / version that has created this alert:  osm_const_param 1.0.1
     ScW: 274100190010

 603 The pointing hasn't increased by one. From 19 to 21 (2741_0001_AHF)
     -> see 1.1.c)

7000 IREM STANDARD MODE
     Program / version that has created this alert:  Preproc 5.8
     Directory of alert generation:  /isdc2/run/alert/nrt_pp
     IREM SHOULD BE IN INTEGRAL MODE AT ANYTIME, Please verify it's expected to get this mode!
     -> see 1.1.d), 1.1.e)

   * Level 1:

 605 The mode differ for n sec. from the planning
     Numerous alerts for ScWs: 274100180010 - 274100230010,
     274100550010 - 274100710010

     -> see 1.1.c)

 3.2 Parameter out of limits 

     IBIS:
     -----
     Due to Solar minimum, the IBIS veto limits are not appropriate
     resulting in too many alerts
