xronwin is a Perl script This script writes a new or modifies an old XRONOS window file. XRONOS window files are ASCII files and contain values for the different type of windows and text. There are 4 types of windows in the XRONOS window file: * Time : consist of up to 1000 time intervals * Phase : consist of an epoch, period and up to 10 phase intervals * Intensity : consist of up to 10 intensity in bin, newbin and interval * Exposure : consist of up to 1 exposure in bin, newbin and interval When the script is invoked the following menu is displayed: [T] Change TIME Windows [P] Change PHASE Windows [I] Change INTENSITY 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: One of the action in square brackets should be entered. The minimun and maximum values of the Time [T], Phase [P], Intensity [I] and Exposure [E] windows must always be given in increasing order. The different types of window can be specified in any order, the script will give the correct order in the output file. An epoch [DS] and a period [DP] are required when phase windows are selected. If not given, the script displays a warning message. Intensity and Exposure windows can be specified independently for (i) Bins , (ii) New Bins , (iii) Intervals (XRONOS basic time entities), using the option [DB]. When dealing with more than one time series, Intensity and Exposure windows must be specified separately for each series, using the option [DS] and/or using [DW] to copy the current exposure and or intensity window from one time series to another. To read an existent XRONOS window file use the the option [R]. Input files are cumulative therefore many existent XRONOS window files can be read in (via the [R] option) and further modified. All the windows read in, for each type, are added (up to the maximun value allowed) with exception of the Exposure windows for which only the last read or set is accepted. Checking for overlapping windows is done only within the Change options (e.g. [T], [P], [I], [E]). It is therefore recommended, after reading many existing files, that users to check for conflicts (and corrections) using the above options. Entering [S] gives an overview of the current defined windows and after the selection is completed the option [W] writes the XRONOS window file. The values for the phase window range from 0 to 1. Exposure windows consist of a minimum and a maximum exposure level. Units are such that 1 means 100% exposure. The default values for the minimun exposure window in bin, newbin and interval are set to 0. Three formats for time are available to enter time windows: 1. day - enter one number (e.g. 123.524268391) 2. day sec - enter two numbers, the 2nd must contain a decimal point. (e.g. 123 45296.789) 3. day hr min sec msec - enter up to 5 numbers, the 5th may contain a decimal point. (e.g. 123 12 34 56 789) The same rules apply for entering the Epoch for phase windows. Note that time windows and epoch values should be compatible with how XRONOS reconstructs the time. The time used within XRONOS tasks is Truncated Julian Days (TJD=JD-2440000.5) if either (1) the keyword MJDREF is present in the header of the files or (2) if the TIMESYS value is one of the following strings MJD or JD or TJD. If neither (1) or (2) are true, the times are given in days relative to the value found in the TIME column." COMMAND LINE PARAMETERS (all are optional) -h See this message. -i infile Name of the input window file. You may specify a window file containing some starting values that you wish to modify or add to. If you don't specify one, you will get the default values. -o outfile Output window file name. -v Verbose mode.
