!Overview
		  Finding CDS Studies

This program allows one to find CDS study definitions based
on the raster properties.  After setting up the search
criteria, press the FIND button.  The studies which are
found to match the search criteria will appear to the right.

In most of the input text boxes, one can enter in either a
single value or a range of values.  Data ranges are signaled
by using a dash between two values.  For example, if one
wished to look for rasters with exposure times ranging from
10 to 20 seconds, then enter in 10-20.

Multiple wavelengths can be entered separated by commas.

Depending on how this routine was called, the output may be
either the list of study definitions, or the list of
observations made with these studies.

!Detector
Select either the NIS or GIS.  This field is mandatory.

!Slit
Pull-down menu showing the different slits available.  One
can either select a specific slit or all the slits.

!Exposure time
Text box allowing searching on the exposure time.  One can
either enter a single value or a range of values separated
by a dash.

!Maximum duration
Text box allowing searching on the total raster duration.
Only a single value is allowed.  Rasters whose estimated
duration is larger than this value will be rejected.

!Raster size
Text boxes allowing searching on the raster width and/or
height.  One can either enter in single values or value
ranges (in arc seconds).  The height field is ignored for
NIS data.

Alternatively, one can search on the raster parameters.

!Raster parameters
Text boxes allowing searching on the raster parameters:

    NX,    NY:     Number of raster steps in X and Y
    XSTEP, YSTEP:  Raster step sizes in arcseconds

The parameters NY and YSTEP are ignored for NIS data.

!Compression
Pull-down menu showing the different available compression
schemes.  One can either select a specific compression
scheme, or search on all the compression schemes.

!Wavelengths
Text box allowing the input of specific wavelengths (in
Angstroms) to search for.  One can either enter a single
value, or multiple values separated by commas.

Second order lines should be entered as their first order
equivalent.  For example, if one wished to search for the He
II line at 303.8 Angstroms, then the wavelength should be
entered as 607.6.

!FIND
Once the search criteria have been set up, pressing the FIND
button will find all studies matching the search criteria.

!Results
After the FIND button is pressed, the list of studies found
will appear in this field.

One can optionally select specific studies from this list by
clicking the desired studies.  If this is done, then only
the selected studies will appear in the output when the
"Exit/Continue" button is pressed.  The default is to return
all the displayed studies.  Pressing the "Reset" button will
return to the default.

!Reset
Pressing "Reset" will override any selections made in the
"Results" list.

!Exit/Continue
Depending on how the routine was called, the button at the
bottom will either read "Exit" or "Continue".  This button
can be pushed when one is satisfied with the contents of the
"Results" list.
