Class ICP

source code

Instance Methods

__init__(self, path)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

readheader1(self)
Read the tow line summary at the start of the ICP data files.

source code

readiheader(self)
Read I-buffer structure, excluding motors.

source code

readrheader(self)
Read R-buffer structure, excluding motors.

source code

readqheader(self)
Read Q-buffer structure.

source code

check_wavelength(self, default, overrides)
ICP sometimes records the incorrect wavelength in the file.

source code

readmotors(self)
Read the 6 motor lines, returning a dictionary of motor names and start-step-stop values.

source code

readcolumnheaders(self)
Get a list of column names.

source code

readcolumns(self)
Read and parse ICP data columns listed in columns.

source code

genmotorcolumns(self)
Generate vectors for each of the motors if a vector is not already stored in the file.

source code

parseheader(self)
Read and parse ICP header information

source code

summary(self)
Read header from file, returning a dict of fields.

source code

read(self)
Read header and data from file, returning a dict of fields.

source code

__contains__(self, column)

source code

counts(self)

source code

Inherited from object: __delattr__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __str__

Properties
Inherited from `object`: `__class__`

Method Details

init(self, path)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

check_wavelength(self, default, overrides)

source code

ICP sometimes records the incorrect wavelength in the file. Make sure the right value is being used. Be annoying about it so that if the wavelength was changed for a legitimate reason the user can override. L is the value in the file. dectector.wavelength should already be set to the default for the instrument.

readmotors(self)

source code

Read the 6 motor lines, returning a dictionary of motor names and start-step-stop values. E.g.,

M = _readmotors(file) print M['a1'].start

readcolumnheaders(self)

source code


Get a list of column names. Transform the names of certain
columns to make our lives easier elsewhere:
      #1 COUNTS -> counts
      #2 COUNTS -> counts2
      MON -> monitor
      MIN -> time
      Q(x) -> qx, Q(y) -> qy, Q(z) -> qz
All column names are uppercase.

readcolumns(self)

source code

Read and parse ICP data columns listed in columns. Return a dict of column name: vector. If using a position sensitive detector, return an array of detector values x scan points.
