Format for the instrumenter Input to the Activity Plan (IAP)

The IAP will be in the keyword format only (fixed format is no longer used). Note that the keywords as listed below can be specified in any order. However, they must be used as described, and they are case sensitive.

SCIPLAN

The SCIPLAN entry specifies the first level of science planning information, i.e. the overall plan as developed during the weekly and daily science planning meetings. The xyz field which follows SCIPLAN_should be descriptive of a specific science plan. It can be up to 10 alphanumeric characters long, no blanks embedded, but underscores are allowed. This field will be used to specify the occurence of Joint Operations Procedures (JOP). For example, SCIPLAN_JOP_3. All fields described as "strings" contain a maximum of 50 alphanumeric characters, blanks, commas and underscores being allowed.

ENDTIME = End time of the special activity
INSTRUME= Instrument or group implementing the planned activity
SCI_OBJ = Scientific objective, e.g. "Bright Point Studies". (1)
SCI_SPEC= (Optional).  More specific scientific objective, e.g. "Density 
          Profile". (1)
OBJECT  = Generic name for the object planned to be observed, from a limited 
          list of possible objects, e.g., "Bright point". (1)
OBJ_ID  = (Optional).  Unique identifier for the object to be observed.
	  Up to 6 alphanumeric characters, no blank embedded, e.g. BP

PROGRAM

The PROGRAM entry is used to describe the specific programs that the instruments would run to satisfy the scientific objectives of the corresponding SCIPLAN activity: for each SCIPLAN entry, there will be a sequence of PROGRAM entries that represent the details of the SCIPLAN.

          axis, i.e. the direction perpendicular to the vertical axis as
	  used in keyword ANGLE. (2) (3) (4)

          axis, i.e. the direction perpendicular to the vertical axis as
	  used in keyword ANGLE. (2) (3) (4)
PROG_ID = (Optional).  ID number specifying that this observation is part of a 
          continuing series
CMP_NO  = ID number of the coordinated observing program that this 
          observation supports
DISTURB=  (Optional).  Description of any possible disturbances
JITTER_LIMIT= (Optional).  Maximum amount of jitter allowable for this 
               program and this instrument (in 1/10 arc-seconds)

(1)  String.  The list of objects is provided below.
(2)  This field can be repeated if nercessary.  The value can be an array of 
     n elements: elements separated by a comma, no blanks embedded.
(3)  Units for coordinates are arc-seconds from Sun center and degrees from 
     Solar North for angles.
(4)  Optional.  Applies to coronal instruments only.

ACTIVITY

The ACTIVITY entry is used to specify predefined activities that the ECS planning system knows about, that is that have been entered in the knowledge base. These activities typically have constraints associated with them that are checked by the scheduling system. The xyz which follows ACTIVITY_ is the name of the predefined activity.

ACTIVITY_xyz (1)
STARTIME= Start time of the special activity
ENDTIME = End time of the special activity
INSTRUME= Instrument or group implementing the planned activity
AMOUNT  = (Optional).  Should be specified for certain activities such as 
          jitter (1)
Notes:
(1)  Example for jitter: specify the amount of jitter generated by this 
     activity estimated in 1/10 arc-seconds.

INST_IIE_MASTER and INST_IIE_RECEIVER

These entries are used to plan the role individual instruments in the Inter-Instrument Exchange (IIE). They are first included in the IAP for planning and coordination. The INST_IIE_MASTER entry is used by a given instrument to indicate that this instrument will be master for the specified period of time. The INST_IIE_RECEIVER entry is used to specify that an instrument will be receiver for the specified period of time.

INST_NRT_RESERVED 
STARTIME= Start time of the reserved time NRT commanding activity
ENDTIME = End time of the reserved time NRT commanding activity
INSTRUME= Instrument which will have  reserved time
CMD_RATE= Expected average number of OBDH block commands per minute 
          between the start time and end time
STATUS  = Acceptance status for this activity (1)

INST_DELAYED_CMD

The INST_DELAYED_CMD entry is used to specify a time window during which a group of delayed commands must be uplinked.

INST_DELAYED_CMD
EARLIEST= Earliest uplink time
LATEST  = Latest uplink time
INSTRUME= Instrument which will performed the delayed commanding
