Spectral Line Standards Database Interface

If you are at the JAC you may wish to use the perl/Tk based interface
which is available by typing 'standards' at the command prompt.


Select Receiver:

Select source: W3(OH) L1551-IRS5 CRL618 OMC1 N2071IR OH231.8 IRC10216 16293-2422 NGC6334I G34.3 W75N CRL2688 NGC7027 N7538IRS1 ATMOSPHERE

Instructions:
Select the desired receiver, source and transition. The list of transitions will change automatically with the choice of receiver.

Upon clicking 'Go' a new window will open in which a graph will be shown with all the matched observations. Note that it may take a little time for the graph axes to be draw (it is complete when the mouse stops showing a 'clock' symbol). This will also show the mean and various other basic statistics.

Within this window moving the mouse over any points in the graph will pop up basic information about the observation. Left clicking on the points will open up another window in which the spectra itself will be displayed.

Also within the window with the graph of all matched points it is possible to press and hold the left mouse button (whilst not over the top of a point) and drag out a box (you must drag from top left to bottom right). Once the box has the desired shape left click within it and that area will be zoomed. If you get the shape of the box wrong click any where else in the graph and the box will be deleted, you can then try again. Within a zoomed graph right click anywhere to zoom back out.

The window that displays the actual spectra does a crude automatic baseline removal and also shows two vertical lines that show the area within which the integrated intensity was calculated (as used to plot that spectra's position on the graph).
