... Circles are used to depict the source positions. ... A optional ID label can also be displayed alongside the circle, corresponding to the row num- ber of that source in the input source list. ... These circles are in fact DS9-type regions, which can be written out to a le for future use (for example, when running a later DS9 session) by setting withregionfile to true, and specifying the desired le name via the regionfile parameter. ... This is a text le containing region descriptions for each source...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ... Parameters can be fixed using the fix option of the regions public access point (for fixing classes of markers) or by means of a fix keyword in the definition of an externally loaded marker. ... In the command: echo "regions fix all -position -size" | ...

... Here we will continue to look at line plots. ... Handling Missing or Bad Data in Line Plots . ... IDL has a number of ways to position line plots and other IDL graphical displays in the display window. ... In IDL, the !P.Multi system variable can be used to create multiple plots in a display window. ... P.Multi(0) . ... IDL> plot, num, line, linestyle=0 . ... IDL> badData = line . ...

Many entry fields permit sexagesimal entry (h:m:s.s or :':"). ... Sexagesimal entry is flexible in that you can specify one to three fields, as you desire. ... Position entry widgets assume that a single field is decimal hours or degrees (h.h or . ... You may specify one to three fields: . ... Note: sexagesimal offsets and durations are entered in the same fashion, but a single field is decimal arc-seconds or seconds ('.' or s.s) and two fields are (arc) minutes and seconds (':"." or m:s.s). ...

SUBJECT=4: DOCUMENT= Give name of doc. to print: [return to menu] Send this document to a printer selected with PRINTER= The '*' character can be used as a wildcard, f.i. DOCUMENT=*gauss* prints all documents with 'gauss' in its name. ... For the subjects 4 and 5 (print documentation and purpose lines from documentation) a document name is wanted. ...

... To run the <LAYER> version of the example, select: flower.htm . ... However, if the page had several layers with absolute positions, and you wanted to place another layer in a relative position to one of the existing layers, you could use inline JavaScript to calculate the value for LEFT or TOP . ... In this example, there is really no need to use inline JavaScript to position the last flower layer, since you could just let the TOP value default to its natural value, as in the other flower layers. ...

... JavaScript 1.2: added name , text , x , and y properties Using the HTML A tag or calling the String.anchor method. The JavaScript runtime engine creates an Anchor object corresponding to each A tag in your document that supplies the NAME attribute. It puts these objects in an array in the document.anchors property. ... A string specifying the anchor's name. text . ...

... Restrictions ) are used. If specified form of output is EMP then astrometric equatorial coordinates are printed in the form usual for Ephemerides of Minor Planets, with formal precision of 0.01 minute of time in R.A. and 0.1 minute of arc in declination. ... It should be noted that the near-opposition ephemerides are not calculated for bodies/ points with numbers from –12 to 0 (in case they are included into task for computation of such ephemerides only their names are displayed in the results). ...

HEIGHT="height" specifies the height of the layer's clipping region and serves as the reference for setting the relative height of children layers. ...

... We present a new Tcl/Tk based GUI interface tool which features plotting of curve and image data and allows for user input via return of regions or specific cursor positions. ... Curves and Images may then be combined to form a displayed Graph. ... With the development of several GUI based tools for High Energy Astrophysics at the HEASARC, we found a need for a interface tool that supports combined curve plotting and image display in a native Tcl/Tk environment. POW is our answer. ...
