WindowsXRONOS supports four different types of windows :
Time and Phase windows are applied to Bins. Only those bins whose center time is within the start and stop of a time window or phase window (for a specified epoch and period) are accepted.
Intensity and Exposure Windows can be specified independently for:
(i) Bins , (ii) New Bins , (iii) Intervals. Intensity and Exposure
windows are applied first to Bins, then Newbins and finally to
Intervals as specified. When dealing with more than one time
series, Intensity and Exposure Windows must be specified
separately for each series.
xronwinThe xronwin task can be used to interactively generate window files for usage with XRONOS tasks. The interface is fairly simple, starting at a main menu:[T] Change TIME Windows [P] Change PHASE Windows [F] Change FLUX Windows [E] Change EXPOSURE Windows [R] READ an Input file [S] SHOW All Defined Windows [C] CLEAR All Defined Windows [W] WRITE Window file [Q] QUIT Window Program [DS] Define Series Number (Currently 1) [DB] Define Bin Type (Currently Orig. Bins) [DE] Define Epoch for Phase Windows (Currently Undefined) [DP] Define Period for Phase Windows (Currently Undefined) [DW] Copy Defined Windows from Series to Series Choose an action:To define TIME, PHASE, FLUX (aka Intensity), or EXPOSURE windows type the appropriate letter. For example, selecting "F" results in a list of the existing Intensity windows and a prompt: Current Intensity Windows for Original Bins Series 1 are: Window Minimum Maximum 1 20 1000 [A] add more windows [#] delete window number # <RETURN> to main menu Action:Pressing the number of a window followed by <RETURN> deletes the window, while selecting "A" makes xronwin prompt for window min/max values. It will continue to prompt for windows until <RETURN> is pressed with no answer or the maximum number of windows is reached. Options starting with "D" define settings which certain windows depend on. For example, phase windows require an Epoch (DE) and Period (DP) to be defined, while intensity and exposure windows use the series number (DS) and bin type (DB). From the main menu, press "W" followed by <RETURN> to write the file. The new file will end with ".wi", and may be used with XRONOS tasks through the parameter, window (e.g. "lcurve window=winfile.wi"). Also, the name of the file may be entered at the prompt which asks for "Name of the window file". xronwin WalkthroughExecuting the xronwin script (Screen output is in a fixed width font, while commentary is italicized):> xronwin [T] Change TIME Windows [P] Change PHASE Windows [F] Change FLUX Windows [E] Change EXPOSURE Windows [R] READ an Input file [S] SHOW All Defined Windows [C] CLEAR All Defined Windows [W] WRITE Window file [Q] QUIT Window Program [DS] Define Series Number (Currently 1) [DB] Define Bin Type (Currently Orig.

Checks are made to see that the start is less than the stop time. Windows, however, need not be entered in chronological order. Pressing <RETURN> with no value exits window entry.
