ill do another try with smaller values inside the punchout(n). im sure the results will help me out for more ideas around this problem

punchout_tukey(6/0.0005/0.0005);connes;rectangle;hamming;gauss(0.0005);blackman;rectangle

punchout_tukey(4/0.0005/0.0005);connes;triangle;hamming;gauss(0.0005)

punchout_tukey(4/0.0005/0.0005);blackman;rectangle;hamming;gauss(0.0005);flattop

punchout_tukey(5/0.0005/0.0005);hamming;triangle;connes;gauss(0.0005);bartlett

punchout_tukey(5/0.0005/0.0005);kaiser_bessel;rectangle;bartlett_hann;gauss(0.0005);hann

punchout_tukey(5/0.0005/0.0005);bartlett_hann;triangle;hann;gauss(0.0005);nuttall

punchout_tukey(5/0.0005/0.0005);hamming;rectangle;blackman;gauss(0.0005);rectangle

punchout_tukey(5/0.0005/0.0005);hamming;blackman;rectangle;gauss(0.0005);blackman_harris_4term_92db

punchout_tukey(4/0.0005/0.0005);connes;triangle;hamming;flattop

punchout_tukey(4/0.0005/0.0005);blackman;rectangle;kaiser_bessel;hamming

punchout_tukey(4/0.0005/0.0005);nuttall;triangle;hamming;blackman

punchout_tukey(4/0.0005/0.0005);flattop;blackman;rectangle;blackman_harris_4term_92db
