Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... The previous example, Chapter 12, "Expanding Colored Squares Example," illustrates how to expand and contract the clipping region of a layer without changing the wrapping width of the layer. This example illustrates how to capture mouse events so that the user can make a layer's wrapping width wider or narrower by dragging the mouse. ... how to capture mouse events for a layer . how to change the wrapping width of a layer by using the load() function . ... Capturing Events for the Layer . ...

... HST . Changes to CALSTIS Software and STIS OTFR Products . ... Data . ... HST Overview . Overview . ... This build includes version 2.17b of the CALSTIS code for use in the On-The-Fly-Recalibration (OTFR) pipeline for STIS data products. This makes the pipeline products more consistent with data recalibrated with version 2.17 of CALSTIS which was released as part of STSDAS version 3.3. ... Version 2.17b of the CALSTIS code does contain two important fixes to errors in version 2.17: . ...

... As mentioned above, in an emergency ^@ can be used instead of ^M. When SM is started, or whenever the TERMTYPE command is used to change terminals, the arrow keys are bound to the commands previous_line , ext_line , previous_char , and ext_char . ... this won't work (you'll get a syntax error) and you'll have to use the next alternative, namely put the commands into a file and say read edit filename , for example: # Change the history character # name key history_char ! ...

... Finding Stars . ... Handling Bad Pixels . ... The guide camera image controller can control one or more guide cameras. ... Each time the camera is read, the image is automatically saved to a fits file on a shared disk. ... Cameras that have bad pixels require "bad pixel maps" in order to find stars, centroid or even compute statistics for the image. ... View this image (for instance in NIH Image) and determine an upper and lower cutoff; pixels whose values are outside of this range are considered...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
