PHASE_PRECISION

#define PHASE_PRECISION   0.1

Class for storing Optimal Filtering Coefficients (OFCs) in a coral::Blob.

This class extends the header defined in TileCalibDrawerBase by two additional 32 bit words:

• nSamples: The number of samples used in OFC computation
• nPhases: The number of phases stored in the BLOB.

Directly after these two extra header words a list of phases is stored. The phases are encoded as integers so that exact comparisons are possible. Since phases are only needed with a resolution of 0.1ns, a good convention is to store int(10*phase).

If the nPhases is set to a negative value in initialization with init(...), only one list of phases common for all ADCs is stored.
