Detailed Description

A transient data structure for clusters in TPC-native pad, and time format. To keep it as small as possible, row coordinate is kept outside in the meta information for a sequence of ClusterNative objects.

Structure holds float values in a packed integral format, scaling factors are chosen according to TPC resolution. The 24-bit wide time field allows unique values within 512 TPC drift lengths.

Not for permanent storage.

Returns

Returns the pad position of the cluster. note that the pad position is defined on the left side of the pad. the pad position from clusters are calculated in HwClusterer::hwClusterProcessor() around the centre of gravity around the left side of the pad. i.e. the center of the first pad has pad position zero. To get the corresponding local Y coordinate of the cluster: Y = (pad_position - 0.5 * (n_pads - 1)) * padWidth example: the pad position is for example 12.4 (pad_position = 12.4). there are 66 pads in the first pad row (n_pads = 66). the pad width for pads in the first padrow is 4.16mm (padWidth = 4.16mm). Y = (12.4 - 0.5 * (66 - 1)) * 4.16mm = -83.616mm
