The first option at the top of the menu is the SWEEP FILES widget.
This option allows the user to view what files are currently stored in the
DORADE_DIR and allows the user the option to choose a specific sweep to
display. To get this widget hold down the mouse button and move down until
SWEEP FILES is highlighted. Then release the mouse button. The Following
widget should appear.
Allows user to close widget without accepting any changes made while
it was open..
Frames are numbered with the top left being 1,top right 2, bottom
left 3 and bottom right frame 4. This number shows the frame in
which the widget was brought opened from.
Brings up a window showing a list of what radars have data in
the current data directory. If there is more than one radar in
the directory you can select one by clicking on it. Once one has
been selected then only the sweep files for this radar will show
up in the Sweep List. Clicking in this button causes a rescan
of the directory.
Clicking here brings up a window listing all the sweep files in
the current data directory for the selected radar. The sweep
file names contain the date and time of the sweep. They also
display the radar name and the last part of the file name gives
the elevation angle of the sweep. In order to select a sweep
for displaying you click on the one you want and the
window goes away. To make the window go away without selecting
a sweep click on the SWEEP LIST button again. You must select a
new radar name from the Radar list button in order to see the
sweep(s) pertaining to it. Clicking in this button causes a rescan
of the directory.
There is a limit to the number of files that can be viewed in the
sweep list. This limit is apparently undocumented in the X-Window
Systems literature. It may be on the order of 2000 or perhaps as high as
3700. This limit is likely to be architecture and window system
dependent. Since solo periodically rescans the directory (every 7
hits) to recreate an internal data base for each radar ordered by time
and version number and a rescan is also executed at the end of each
editing pass, it might be prudent to try and keep the number of
sweep files lower. Perhaps not exceeding 1000.
Closes the widget accepting the changes made while it was open. Any
changes made in a widget will not show up in the frame(s)
until they are re-displayed. To do this click on the = sign
in the control bar for each window you made changes in.
Also clicking on the colored box at the bottom of the control
bar will cause all windows with the same colored box to update.
The color of the box is a code to show which frames are locked
together. See Arrow Buttons
for more details on the displaying tools.
This number is referenced by the arrow
buttons on the control bar. The arrows allow the user to
move forward and backward through the
sweep files. The input scan interval is the number of sweeps
skipped each time an arrow is clicked.
See Editing text for details
on changing this number.
When this button is toggled, sweeps selected from the sweep list will
immediately plot without clicking in the "ACCEPT" button.
Brings up the following widget accompanied by the
ALL_FILES_LIST and the SELECT_LIST which facilitate the removal of
unwanted sweeps. The ALL_FILES_LIST lists all the sweep files in the
directory and the SELECT_LIST contains a list of sweep files that will
be subject to some action.
Clicking on a line in the ALL_FILES_LIST will cause the file to appear
in the SELECT_LIST. Clicking on a line in the SELECT_LIST will
simply remove the file from the select list.
The number to the right of Delete All But The Last
indicates the number of files that will not be deleted that have time
stamps earlier than the current sweep. All other files that have
earlier time stamps that are not in the Preservation List will be
deleted when the OK TO DELETE button is clicked.
This capability is useful is
you want to peruse data but not accumulate a lot of sweep files. If
the translaters are setup to read in a certain number of sweeps and
stop, then you can repeatedly run the translaters and use this option
to keep the number of sweeps on the disk to a minimum.
List All Files causes the ALL_FILES_LIST and the
SELECT_LIST to refresh on the basis of the Delete All
But The Last number.
Clear Select List removes all entries from the
SELECT_LIST.
List Only Preserved Files lists the sweep file names in
the Preservation List.
Mark These Files for Preservation
causes files in the SELECT_LIST to be entered in the Preservation List.
Remove These Files from Preservation
causes files in the SELECT_LIST will be removed in the Preservation List.
Delete All But the Selected Files
causes all sweep files except the ones in the SELECT_LIST to be deleted.
OK TO DELETE
causes all sweep files in the SELECT_LIST will be deleted. File names
appear in the window from which you invoked solo as they are deleted.
Adds the current sweep to the Preservation List.
The Preservation List is a list of file names placed
in a file in the same directory that contains the sweep files and
actions eminating from the Delete Some Sweep Files
widget will not affect files in the preservation list. The UNIX "rm"
command does NOT consult this preservation list.
Shows the current data directory. Also allows user to change to
a new directory that contains additional sweep files. Edit the
path then click on Sweep List to see files contained in this new
directory.
Gives the name of the sweep currently plotted in the frame
this widget was opened from.
The number buttons on the right side of the widget refer to
the display frames. The numbers which are highlighted in pink
are the frames that will receive the changes made in this
widget when closing with the accept button. You can use the
mouse to click on and off each number except the frame in
which the widget was brought up from.
The horizontal aspects of time series plots are determined by the
start time and end time
exclusively. The time interval implied by the start and end times is
remembered when the forward button is clicked and both the start and
end times will be shifted forward by the time interval. The same for
moving backward. Also clicking on a sweep in the
Sweep List will cause the time series
start time to become the
time to the nearest second to the start time of the sweep and the end
time becomes the start time plus the time interval from the last plot.
This widget pops up with the
SWEEP FILES Widget when time series
plots are turned on in the
VIEW widget.
There is more than one way to define a start time. For example if the
start time is currently 23:34:01 and the end time is currently
23:34:11 implying a plot spanning 10 seconds and the user wishes to
begin the plot at 23:35:00, it is sufficient to type 23:35 and the
plot will begin at 23:35 and plot for 10 seconds. There is no need to
type the date unless crossing midnight and no need to modify the end
time.
Another way to affect the start time is to type a relative
time. Typing "+2.5m" next to start time will cause the start time to
be shifted two and one half minutes from the current start time.
A user can also use "h" for hours
and an optional "s" for seconds. Relative time is assumed if the
number is preceeded by a "+" or a "-".
For information and shortcuts on typing text in widgets,
see Editing Text In Widgets.
Changing the end time permits the user to change the time span of the
plot. The easiest way is to use a relative time described above, but
a user can also type an explicit end time. The information in the start
time is always analysed first and relative times will be relative to
the current or newly modified start time.
