Constructing Plot and Table URLs by Hand

The SLD WebTables System is mainly used to provide access to data from the following Oracle tables: All of these tables currently reside on SLAC Central Unix.

Most of the elements in these tables are already available from one of the standard interfaces. But even if an element from one of these tables is not yet in the interfaces, you can still access it through WebTables. You can even access information from tables that are completely unknown to the WebTables system.

In these cases, and for other special purposes, you will need to construct the plot or table URL by hand. This is best done by first using the normal interfaces to make a plot or table that is similar to what you want, and then modify the resulting URL to get what you really want.

Read the following explanation of the URL and then pay careful attention to the list of additional restrictions that apply for datanames that are not known to the WebTables system.

A typical table URL is as follows:

The relevant parts of the URL are delimited by slashes. They are as follows:

Abbreviations for Oracle Owner.Table Names

To keep the URL from getting too long, the datanames that are currently known to the WebTables system can have their Oracle Owner and Table names abbreviated as follows.

Datanames that are Not Known to the WebTables System

Datanames that are not currently known to the WebTables system can still be accessed through WebTables.
Not only can you reference elements that are not currently known to the system, but you can reference elements from whole tables that are not currently known to the system.

Since the WebTables system has less information to go on for these datanames, the following restrictions apply:

If the entire table is currently unknown to the system, the following two additional notes apply: When you reference completely unknown tables, it doesn't matter what form title you specify in the URL. Just use any existing form title (e.g., SLD or CATER).

Raw Table Output Suitable for Export

If the URL is modified to change "TABLE" into "TABLE^RAW", the output is done in a form that is suitable for export to other applications.

You can then save the output as plain text by using your browser's "save as...". It only remains to cut off however much of the top of the page that you don't want. Everything after that is straight columns of output.

You can alternately save the output by using the cut and paste features of your desktop.
