The User View is where you will have the most interaction directly relating to the application. It is essentially divided into two different aspects: the Query Aspect and the Chart Manipulation Aspect.
Query Aspect
In these fields, you will have the ability to input the appropriate values to grab information from the database that revolve around a given RA and Dec. Required fields are denoted by an asterisk, any errors in the validation will be denoted by an "X" within a red circle, and possible errors/warnings will be denoted by an "!" inside of a yellow triangle.
Catalog
The catalog field currently has 3 different databases to choose from: GWAVES (default), UCAC2, and UCAC3. The GWAVES database is a combination of UCAC2 and UCAC3 but will only return information about the objects that are present in both UCAC2 and UCAC3. UCAC2 and UCAC3 are comprised of the raw data compiled by the USNO. Their range in Declination is limited to that of each catalog but will return all the raw data on each returned object.
...
These fields, mostly buttons and checkboxes, will allow you to manipulate the chart on the Image View and how the data is represented. Additionally, each action, and a couple extras not included in the user view, are able to be executed through shortcut keys.
Rotate Instrument
...
Trace Crosshairs toggles the cursor when over the graph. If it is on, crosshairs will intersect at the cursor's location. Otherwise, it will display as a normal cursor.
Guider/WFS
"Guider" and "WFS" are toggle buttons in that when one is selected, the other is deselected. Provided the catalog queried is GWAVES, the selected object is converted either into a Guider Star or a Wavefront Sensor. If the catalog is something other than GWAVES, then these buttons have no functionality.
Reset Graph
"Reset Graph" will reset the graph to its original size and re-centered on point of query. The instrument's angle of orientation will be set to 0.0, any object selected will be unselected and the annotations and cross hairs will be toggled off.
Send Coordinates
"Send Coordinates" will send the selected object's data, in XML format, to the intended instrument. If the GWAVES catalog is selected, the XML data will note whether the object is a Guide Star or a WFS.
Counters
The last two counters are more for the query. They display how many objects were found vs. how many were returned.
