Hi Stijn
I got one question regarding to the structure you used in the python script for reading ascat .dat file and .idx file. Basically it is the .ipynb script.

struct2 = np.dtype([('jd', np.double), ('sig', np.float32), ('sig_noise', np.float32),
('dir', np.dtype('S1')), ('pdb',np.ubyte), ('azcorr_flag',
np.dtype([('f', np.ubyte),
('m',np.ubyte),
('a', np.ubyte)]))])
f = open(''.join(["./", filename, ".dat"]), "rb") # reopen the file
f.seek(208, os.SEEK_SET) # seek
data_1 = np.fromfile(f, dtype=struct2)

How did you decide the structure of the struct2? I mean is there any method to see whether a .dat of ASCAT data got different structure rather than what you showed here?

Thanks and hope for your early reply!
Sincerely
