The LONG-RANGE PLAN, SCIENCE OBSERVATIONS Report is the principal means of
communicating to observers which exposures are to be executed during each week
in the upcoming year.  The Science Planning Branch revises The Long-Range Plan
and posts it on STEIS on a weekly basis. The report contains science
observations from General Observer (GO), Guaranteed Time Observer (GTO), and
Science Assessment (SAT or SAO) proposals which are grouped and ordered by
week.

Observers may use the Report to identify the week during which we plan to
obtain their observations.  Observers may also use the Report to identify when
their presence at STScI may be necessary for real-time contacts with the
spacecraft. 

Because the long-range plan is a projection for the coming year it must be used
with caution.  It will be revised on a rountine basis, as necessary, in response 
to operational experience, to reschedule observations which were not 
obtained when first planned, and following monthly progress reviews. 

Three weeks before the beginning of execution of each weekly Science Mission
Specification the detailed scheduling of observations in that week will be
completed by the Science Planning and Scheduling Branch.  Some observations
planned for a particular week (and listed in the Long-Range Plan) will not be
schedulable due to operational constraints which could not be considered in the
long-range planning process.  The final observing schedule for each week may
be found on STEIS in the observer/weekly_timeline directory. 

The report file is ASCII and the report is in 132-column format with tab
separated columns.  In general, proposal types, PI names, titles, and targets
have been truncated to meet the requirements of the fixed fields in this
electronic report.

       		EXPLANATION OF COLUMNS OF REPORT

SMS (column 1)
--------------
	The week for which an observation is planned is identified by
the name of the Science Mission Specification (SMS).  SMS names are in
the format YYDDD where YY is the year and DDD is the day of year of
the first day in the SMS.  Generally SMSes begin at 00:00 UT each
Monday. 


Type (column 2):
----------------
	General Observer (GO), Guaranteed Time Observer (GTO), Science
Assessment (SAO or SAT), and Early Release Observations (EROS) program
types are identified.  For GTO programs the Investigation Definition
Team is also identified (AST = Astrometry Science Team, FOC = Faint
Object Camera, FOS = Faint Object Spectrograph, HRS = Goddard High
Resolution Spectrograph, HSP = High Speed Photometer, OS = Observatory
Scientist, WFC = Wide Field Camera). 


PI (column 3):
--------------
	The last name of the program Principal Investigator is given.


Title (column 4):
-----------------
	The title of the program is given.


ID+SUNIT (column 5):
------------------
	The proposal ID assigned by the Proposal Entry Processor (PEP) 
system.	

	Exposure Logsheet lines are logically grouped into scheduling
units (SUNITs) as a part of the process of TRANSFORMATION (the program 
that transforms PEPSI proposals into commands for the telescope).  The SUNIT
identifiers are reported in this column. 

	The format for this field is PPPPII where PPPP is the proposal ID and 
II is the SUNIT ID. 


Target (column 6):
------------------
	The target appearing in the TARGET column is the first
external target appearing in the sunit, but may not be the only
target, although normally, there will not be more than one external
target per sunit. 


Instrument (column 7):
---------------------
	The scientific instrument used for an exposure within an SUNIT.
