Stand-alone peak storage class.
Acts as a list of information records of peaks. Information stored is:
- i
rough intensity
- sigi
rough standard deviation in intensity
- x
vertical pixel coordinate of the peak
- y
horizontal pixel coordinate of the peak
- mmx
horizontal mm coordinate of the peak
- mmy
vertical mm coordinate of the peak
- mmxid
horizontal mm coordinate of the peak if the detector
alignment would be ideal
- mmyid
vertical mm coordinate of the peak if the detector
alignment would be ideal
- radius
for strong peaks, an estimate for the single sigma spot radius
- highpixel
the highest pixel value in the peak
Optionally, a record of extra data can be stored as the rec attribute.

__delitem__
|
__delitem__ ( self, i )
List emulation, delete element i |
|
|
__getitem__
|
__getitem__ ( self, i )
List emulation, retrieve element i |
|
|
__getstate__
|
__getstate__ ( self )
Return the object in a storable form |
|
|
__init__
|
__init__ (
self,
p=None,
dx=None,
theta=None,
dis=None,
hardware=None,
rotaxis=None,
)
Builds an empty list.
arguments:
- p
the position of the detector (only dx and theta are used)
- dis
distortion calibration object
- rotaxis
the direction of the rotation axis (needed to calculate chi)
alternative arguments if p is not given:
- dx
the dx position of the detector
- theta
the theta position of the detector
- hardware
the hardware connection object
This class does not use the p argument (subclasses do), but the
dis argument is required for proper operation.
