Module functions for ignoring source and background filter ranges in 1-D datasets.
Integer_Type set_ignore([Integer_Type],Float_Type,Float_Type)
Integer_Type set_signore([Integer_Type],Float_Type,Float_Type)
Integer_Type set_bignore([Integer_Type],Float_Type,Float_Type)
Success/Error Return Values: 1/0
Arguments:
(1) Dataset number (default 1)
(2) The lower bound for the ignore range (default no lower bound)
(3) The upper bound for the ignore range (default no upper bound)
The commands set_ignore, set_signore,
and set_bignore allow the user to specify data ranges
to ignore in both source and background datasets, a source dataset, or
a background dataset respectively. These functions may only be applied
to 1-D data. Use
set_ignore2d to
set exclude regions in images.
Note that these functions work in the space given by the current
ANALYSIS setting, e.g., if the setting is
ENERGY, then the defined bounds are assumed to be in
energy units. Note that in CIAO 3.1 set_ignore will
work only if instrument models for both source and background are set.
See the related Sherpa commands
NOTICE
and
IGNORE
for more information.
Read in a PHA file with instrument; ignore the lowest-energy channels:
sherpa> () = load_dataset(1,"example.pha")
sherpa> set_ignore(1,,0.3)
1
sherpa> ANALYSIS
Analysis Space for Dataset 1: Energy
In this example, all data below 0.3 keV are ignored in dataset 1.
Continue Example 1,
ignoring all data between 6 and 12 Angstroms:
sherpa> ANALYSIS WAVE
sherpa> set_ignore(,6,12)
1
Continue Example 2,
now ignoring all source data above 9 keV:
sherpa> ANALYSIS ENERGY
sherpa> set_signore(1,9,)
1
The corresponding background data above 9 keV are still noticed.
