public class LinCal
extends java.applet.Applet

LinCal is an applet designed to show when observing runs are scheduled and to give some basic information about these runs. The main display has a ScrollPane that shows the phase of the moon and what runs are scheduled on a given night. More detailed information about a run is shown when a user clicks on a run, and a night summary can be obtained by clicking on the date. At the bottom of the main display is a row of buttons that bring up windows allowing the user to control the way the runs are displayed, etc.

Priveleged users may (after logging on through the "Log On" button) add/delete/modify runs on the calendar.

Each day in a run is represented by a SearchBlock that looks something like , , or

The first represents a run that has been scheduled, the second is a proposed run, and the third is a run that is queue scheduled. In all the SearchBlocks, the first line is the name of the telescope, and the second is the type of run (search, photometry, spectra, etc.). The color is fairly arbitraty, but has something to do with where the telescope is located.

Clicking on a SearchBlock brings up a window that shows a bit more about a run. It looks something like:

The Observing Days show which days are included in the run, along with what fraction of the night is available for observations (0-1).

If the user were logged on (with database access priveleges), the Group and Observing Days TextFields would be editable, and the "Add Day" and "Send" buttons would be active. Such a user may change/delete the run dates and add more days. Clicking on the Send button updates the database with any changes. The reload button restores the fields as per their current database status.

Clicking on the "Sort..." button brings up a window such as:

To perform a sort, first select what parameter to sort by (group, type, or telescope), then number the entries in the order you wish them to be displayed. If a field is blank, negative, or not an integer, it will not be displayed. Giving the same number to one or more fields will group them together. Next click on "Do Sort" to reload the calendar, sorted as you have indicated. Select "NONE" on the Sort By Choice to perform no sorting, and pack all runs to the left (all dates in a run are shown in the same column).

The information below pertains to the java sorce code for the applet only and is not vital for its use.
