Possibility of the first segment as the longest one of frequency range after jump correction

[ghraecakter]

Hi Lili,

After jump correction, the frequency range is divided into multiple segments by jump points.
However, your code neglects the possibility that the first segment being the longest

pyaftan/pyaftan.py

Lines 633 to 634 in 976efd2

	indx = np.where(np.abs(trig)>0.5)[0]
	indx = np.append(indx, nfin-1)

I'm wondering if you deliberately did it or overlooked Misha's original code

pyaftan/aftanf77/aftanpg.f

Line 392 in 976efd2

indx(1) = 1

If it's the former case, my guess is that you always want to save the longer periods.
If it's the latter, a possible fix would be

indx = np.concatenate(([0], indx, [nfin-1]))

Best,
Shane
