isChannelDead()

bool DeadChannelsManager::isChannelDead	(	RPDetId	detectorId,
		unsigned short	stripNumber
	)

This function answers the question whether given channel is dead or not. RPDetId - detector ID given in raw form, this function has to convert raw ID to symbolic stripNumber - ID of the strip, it is a number from range <0; 511>, this function has to convert it into a vfat ID and a number from range <0; 127>

It is assumed that: channels 0 - 127 are in vfat number 0 channels 128 - 255 are in vfat number 1 channels 256 - 383 are in vfat number 2 channels 384 - 511 are in vfat number 3
