Setting The Time Domain

The time domain settings determine the range of values that are downloaded from the database. The user can set all the mnemonics at once to the same domain or each mnemonic can be given its own domain. The time is written in the "spacecraft" format, with the second and millisecond count left off.

When the program is first started, the year fields are filled with the current year, the DOY and hour fields are blank and the minute fields are set to "00". The user will normally only need to fill in the day of year and hour of day fields.

To set the time domain on the Data Selection page:

1. Go to the Select Time Domain area of the page.

Click on the graphic for more information.

2. Fill in the time fields by one of the following methods-

1. Type-in method (The cursor will automatically jump to the next field when the user enters the last digit in each field. The tab key can also be used to move from one field to the next.)

1. Go to the Start Time area

2. Enter the year in the first field. (Default = current year)

3. Enter the DOY. (No default setting)

4. Enter the hour of the day. (No default setting)

5. Enter the minute of the hour. (Default = 00)

6. Repeat steps ii - v in the End Time area.

2. Copy-Paste Method

1. Copy a time stamp in spacecraft format to the clipboard,

2. Left-click in one of the time fields,

3. Right-click in that field to bring up the pop-up menu,

(This menu can also be used to copy the current time domain setting to the clipboard)

4. Select the Paste Data-Time menu item. All the fields for the start time (or the end time) will be filled.

5. Repeat steps i - iv for the other set of time fields.

The user can combine the two methods outlined here if desired.

3. Accept the time setting by either:

• Click on the Set Time button if you want to use these settings for the currently highlighted mnemonic in the Selected Mnemonics list. Repeat the above steps for each mnemonic until all have a time domain setting.

• Click on the Set Time All button to use the current settings for all of the mnemonics in the Selected Mnemonics list.

Time domain settings for each highlighted mnemonic in the Selected Mnemonics list are visible in the scrollable text window in the center of the page.

Example settings shown.

The number of mnemonics that have their time domains set is shown in the Counts area on this page.
