Xcalibu

Xcalibu是一个Python库，用于管理校准表格或多项式。它包含一个PyTango设备服务器，以便可选地将其作为服务器运行。

xcalibu.py : Python库 Xcalibuds.py : PyTango设备服务器

Xcalibu的名称来源于该库首次用于处理ESRF的扭摆校准。

示例

TABLE + INTERPOL

import numpy
import xcalibu
calib = xcalibu.Xcalibu()
calib.set_calib_file_name("mycalib.calib")
calib.set_calib_type("TABLE")
calib.set_reconstruction_method("INTERPOLATION")
calib.set_calib_time("1234.5678")
calib.set_calib_name("CAL")
calib.set_calib_description("dynamic calibration created for demo")
calib.set_raw_x(numpy.linspace(1, 10, 10))
calib.set_raw_y(numpy.array([3, 6, 5, 4, 2, 5, 7, 3, 7, 4]))
calib.plot()
calib.save()  # create a file named `mycalib.calib` in your current directory.

TABLE + POLYFIT

import numpy
import xcalibu
calib = xcalibu.Xcalibu()
calib.set_calib_file_name("mycalib.calib")
calib.set_calib_type("TABLE")
calib.set_reconstruction_method("POLYFIT")
calib.set_calib_time("1234.5678")
calib.set_calib_name("CAL")
calib.set_calib_description("dynamic calibration created for demo")
calib.set_raw_x(numpy.linspace(1, 10, 15))
calib.set_raw_y(numpy.array([4.1, 3.5, 3.6, 4.2, 4.5, 4, 3.9, 3.8, 4.5, 4.6, 6, 6.2, 4.7, 5, 4]))
calib.set_fit_order(6)
calib.fit()
calib.plot()
