A number of questions are common to most XRONOS applications.
The following question is issued for input filename(s) :
lc1> Ser. 1 filename 1 +options[.rbf]=>If no filename extension is specified, .rbf is appended by default, i.e. default input files are rate buffers. Up to 50 chronologically ordered input files can be specified for each input series. Up to 10 input file options can be specified for each input file. At least one input filename (for each series) must to be entered. Press return when you have specified all the input filenames for each series.
A summary of the header content of each input file is displayed on the screen. The amount of header information displayed on the screen is controlled by global parameter number 1.
Windows can be specified in most XRONOS applications. Reply y to the following question in order to use the window options:
lc1> Window Options? {y/n} [n]=> y
The first mode is to specify windows interactively (i, the default) or use
a window file (f) created with application win (the user is prompted for
the window filename in this case).
lc1> Interact. or window file {i/f} [i]=>
In the interactive window mode (i), windows can be entered as in application
win. An option is included to write the windows specified interactively to a
window file for future use.
In order to enter windows from a window file file.wi reply as follows:
lc1> Interact. or window file? {i/f}[i]=> f
lc1> Window filename [.wi]=> file.wi
Note that intensity and exposure windows originally specified, e.g., for
series C in the window file file.wi can be reassigned to series 1 of
application lc1 by typing:
lc1> Window filename [.wi]=> file.wi cSimilarly, if intensity and exposure windows for series B and C in the window file file.wi are to be used, respectively, in series 1 and 2 of application ccf, then type:
ccf> Window filename [.wi]=> file.wi b c
The newbin duration (in seconds) is entered by replying to the following question:
lc1> Enter Newbin time (s) or neg.rebinning
of min. Newbin Time [ 214.4 ]=>
The default newbin duration (in square brackets) is such as to produce a single
interval with a fixed number of newbins (typically between 128 and 4096,
depending on the application). For binned input files the newbin duration
cannot be shorter than the longest bin duration in the input files (i.e. the
minimum newbin time). In a number of applications (e.g. psd, pss, acf,
acs, ccf, ccs) the newbin time must be an integer multiple of the minimum
newbin time. The newbin duration is not relevant for applications using epoch
folding techniques. Note that if a negative number is specified, this is
interpreted as the number of times the minimum newbin duration is to be
rebinned in order to give the newbin duration.
The number of newbins which determines the duration of an interval is entered by replying to the following question:
lc1> No. of Newbins/Intv. (max. 65536)
{value or neg.pow.of 2}[ 512]=>
This number, together with the newbin duration, determines the interval
duration and, therefore, the total number of intervals over which the analysis
will be carried out. The number can be specified either as a positive integer
(e.g. 4000) or as a negative integer (e.g. -12), in which case the number of
newbins per interval is the corresponding (positive) power of 2 (e.g.
2**12=4096). The default number of newbins per interval is indicated; this is
usually between 128 and 4096 depending on the application. The maximum number
of newbins per interval which can be used in each application is also
displayed.
The results of the analysis from individual intervals can be averaged in a frame. The following question is issued to specify the number of intervals the results of which should be averaged to produce a frame (and therefore in most cases also an output file and a plot):
psd> No. of Intvs per Frame [ 25]=>In certain applications (e.g. lc1, lc2, lc3, efs) every frame must contain results from one interval only and therefore the question is not issued.
