int makett	(	const char *	fileListPath = "/home/igor/bmnroot/align_new/cfg/run9/9555.noa_rlerr.list",
		const char *	testTaskPath = "/home/igor/data.cache/tt9555.r9_lin3.00.root",
		const char *	testSolPath = "/home/igor/data.cache/tt9555.r9_lin3.00.solution.json",

		const char *	truthSigmaPath = "/home/igor/bmnroot/align_new/cfg/presigmas/psg_r9_lin3-testTruth.json",

Reads real tracks, fits straight lines to them, displaces the detector by a randomly drawn solution and writes out hits lying exactly on the displaced model, together with the solution that produced them. Feeding the result back into align.C tests the solver against a truth instead of against itself.

The truth is drawn from the truth sigmas and obeys the constraints (see BmnAlignTestTask), so align.C must use the same constraints file on the task. The solver's own presigmas play no part here: both aligners below take the truth sigmas as their presigmas, the generator to draw the truth from them, the viewer only to display the task.

Parameters

fileListPath	text file listing the source .root files, one per line
testTaskPath	.root file to write the synthetic hits into
testSolPath	.json file to write the truth solution into
constraintsPath	.json constraints, the same align.C will use on the task
truthSigmaPath	.json truth sigmas in the presigma format; every composite parameter not fixed by a constraint needs one, see BmnAlignPriors::Check()
sigmaScale	truth StdDev = truth sigma * sigmaScale, 0 for the nominal geometry
showTask	kTRUE to reload the generated task and draw it afterwards
seed	PRNG seed for the truth and the noise, 0 for a new one each run (it is logged)

Returns

0 on success, -1 if any stage failed
