If the internet conection or proxy is not correctly configured. Opens a web browser which shows an on-line HTML version of this user’s manual. The menu bar provides acces to some PQL’s capabilities. The additional windows, usually generated by matplotlib than can be copied to the clipboard, Images are displayed in an external well-known application, ds9. PQL Main window contains a Menu bar (1), Tool bar (2), four Tabbed panels (3) and temp_dir = / data2 / tmp # the directory to which temporal results will be saved verbose = True # Run parameters run_mode = Lazy # default (initial) run mode of the QL it can be (None, Lazy, Prereduce)Īlthough the user can edit these values in the config file, some of them can be set easilyįor the complete list of the parameters available on the $PAPI_CONFIG file, see Main config file section. # Next are some configurable options for the PANIC Quick Look tool # some important directories # source = / data1 / PANIC / output_dir = / data2 / out # the directory to which the resulting images will be saved.
The following header keywords are also required: However, and in order to group and reduce observing sequences, The complete definition of the FITS headers can be found on the GEIRS documentation.įor general purpose, such as viewing and simple analysis, only minimal headers Or Multi-Extension FITS (MEF), however MEF are prefered. Because PANIC has a FPA of four detector, the FITS files can be Single Extension FITS (SEF) PQL only supports FITS (Flexible Image Transport System) with two-dimensional Supports FITS images, multiple frame buffers, region manipulation, and many The visualization application used to display the images is SAOImage ds9, which The status and progress of the observation during the night. However, its functionalities have been provided mainly in near-real time to check
#SAOIMAGE DS9 HOWTO OFFLINE#
Offline mode (after the observation, with all data files already stored in the disk) PQL can be operated in both near-real time mode (during the observation) and Option available is to select a set of files and request to shift and align them.
Sky subtraction looking for the nearest N frames around the selected one. For example, you will be able to select a file,Ĭompute some statistics values (background, FWHM, min, max, …) or ask for the In addition, PQL allows you to execute manually in an interactive way Sky subtraction (using N-nearest frames or own sky ) It also incorporates the X Public Access (XPA) mechanism to allow external processes to access and control its data, GUI functions, and algorithms.Only display the FITS image with no processing DS9 is a Tk/Tcl application which utilizes the SAOTk widget set. GUI elements such as the coordinate display, panner, magnifier, horizontal and vertical graphs, button bar, and colorbar can be configured via menus or the command line. DS9 supports advanced features such as multiple frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, rotation, pan, and a variety of coordinate systems. All versions and platforms support a consistent set of GUI and functional capabilities. Versions of DS9 currently exist for Solaris, Linux, MacOSX, and Windows.
It requires no installation or support files. It provides for easy communication with external analysis tasks and is highly configurable and extensible via XPA and SAMP. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. SAOImage DS9 is an astronomical imaging and data visualization application.
