Select option 5 from the BATSE menu to obtain a listing of time intervals
during which BATSE was observing the Sun.  Files recording time intervals 
during which BATSE was in spacecraft night, the high voltage was off, or 
there were data gaps, are updated on a weekly basis and used to determine 
the solar viewing intervals.  The original BATSE predictive ephemeris from
which our database is constructed may be found at website
ftp://grossc.nasa.gov/plan_dat/solar/.

Using the BATSE Ontimes Program:

On entering the program, the user is presented with a menu displaying the 
current settings of parameters and the available commands.  The user either
accepts the default value of a parameter, or changes the value by typing
the first 3 letters of the parameter description, comma, the new value. 
When the parameters are set as desired, the user issues a command (again,
the first 3 letters are sufficient).  Upper or lower case may be used for 
input.  A detailed description of the parameters and commands is given below.

A.  BATSE Flare List Program Parameters:

START TIME - Lower time limit for viewing intervals. Format is YY/MM/DD.
   Default value is 91/04/19,0000 (the earliest BATSE data available). 
   Example:  STA,91/4/23

END TIME - Upper time limit for solar viewing intervals.  Format is YY/MM/DD.
   Example:  END,91/4/27

OUTPRINT - Output device for ONTIMES and PRINT commands.  Options are Terminal,
   Printer, and File.  If File is selected, you will be notified of the file
   name.
   Default is TERMINAL.
   Example:  OUT,PRI

EMAIL ADDRESS - Address for mailing ASCII output.  The first time the user opts
   to have a file mailed to himself, he is prompted for his email address.  For
   the rest of the session, that address will be used instead of prompting the
   user for an address each time.  To mail to a different address, reset this 
   parameter.
   Example:  EMA,SDAC::RICHARD

EXIT - Exit BATSE Ontimes Program.

HELP - Display this help file on screen.  You will prompted for whether to 
   mail this help file to yourself.

LISTMENU - Display the menu.

MAILONTIMES - Mail list of solar viewing times generated by last ONTIMES
   command.  You will be prompted for your email address if you haven't 
   already supplied it.

ONTIMES - Generate list of solar viewing times for times between specified 
   START and END time on output device specified by the OUTPRINT parameter.  

PRINTONTIMES - Print list of solar viewing times generated by last ONTIMES
   command on output device specified by the OUTPRINT parameter.  You will 
   be prompted for whether to mail this information to yourself.
