Package icecube.daq.domcal Description

This package allows programmatic access from Java to the DOM calibration information. The class reads .xdc files which contain DOM calibration data in an XML document and place the information into a Java class. All the programmer needs to do is construct an instance of the Calibrator class with either a URL or an InputStream pointing to the XML object.

The primary utility of this class is to transform the raw ATWD waveform data into volt units. This can be accomplished one of two ways - either:

• Through explicit calls to the getATWDFitParam(int ch, int bin, String param) member function. This provides the programmer with the actual fit information. Note that the fit parameters may vary depending on what the fit model is; currently only the 'linear' fit model is used.
• Through the high-level member function calibrateATWD which takes a raw ATWD buffer array and returns a calibrated buffer array. Please note that the DC bias is not subtracted off in this function. The inverse function decalibrateATWD performs the inverse calibration, taking volts back into counts.

The other calibrations tracked by this class are the front-end pulser calibration, the amplifier gains, and the ATWD sampling frequency.
