pyIntensityFeatures.proc.intensity.find_intensity_boundaries(intensity, glat, glon, sweep_times, alt, min_mlat_base, max_coeff, method='ALLOWTRACE', mlat_inc=1.0, mlt_inc=0.5, un_threshold=1.25, dayglow_threshold=300.0, strict_fit=False)[source]

Find the PALBs and EALBs for a slice of intensity data.

Parameters:

intensityarray-like: Array with dimensions of time x sweep-locations containing the rectified intensity at the auroral daytime pierce point
glatarray-like: Array with dimensions of time x sweep-locations containing the geodetic latitude
glonarray-like: Array with dimensions of time x sweep-locations containing the geographic longitude
sweep_timesarray-like: Array with the starting and ending times of the auroral sweep. Gives the start and end times searched if no sweep is found.
altfloat or array-like: Altitude for the intensity data
min_mlat_basefloat: Base minimum co-latitude for intensity profiles.
max_coeffint: Maximum number of coefficients.
methodstr: Method for converting between geographic and magnetic coordinates. (default=’ALLOWTRACE’)
mlat_incfloat: Magnetic latitude increment for gridding intensity. (default=1.0)
mlt_incfloat: Magnetic local time increment for gridding intensity. (default=0.5)
un_thresholdfloat: Maximum acceptable uncertainty value in degrees (default=1.25)
dayglow_thresholdfloat: Maximum allowable background intensity value in Rayleighs (default=300)
strict_fitbool: Enforce positive values for the x-offsets in quadratic-Gaussian fits (default=False)

Returns:

sweep_enddt.datetime: End time of the data
out_datadict or NoneType: Dict with desired boundary data, if data was found. None otherwise.
max_coeffint: Maximum number of coefficients.
