suncasa.utils.stputils.insertchar(source_str, insert_str, pos)[source]

suncasa.utils.stputils.get_curve_grad(x, y)[source]: get the grad of at data point :param x: :param y: :return: grad,posang

suncasa.utils.stputils.polyfit(x, y, length, deg, keepxorder=False)[source]

suncasa.utils.stputils.improfile(z, xi, yi, interp='cubic')[source]: Pixel-value cross-section along line segment in an image :param z: an image array :param xi and yi: equal-length vectors specifying the pixel coordinates of the endpoints of the line segment :param interp: interpolation type to sampling, ‘nearest’ or ‘cubic’ :return: the intensity values of pixels along the line

suncasa.utils.stputils.map2wcsgrids(snpmap, cell=True, antialiased=True)[source]

Parameters:

snpmap
cell – if True, return the coordinates of the pixel centers. if False, return the coordinates of the pixel boundaries

Returns:

suncasa.utils.stputils.readsdofile(datadir=None, wavelength=None, trange=None, isexists=False, timtol=1, ignoreymdpath=False, suffix='image_lev1')[source]: read sdo file from local database :param datadir: :param wavelength: :param trange: the timestamp or timerange in Julian days. if is timerange, return a list of files in the timerange :param isexists: check if file exist. if files exist, return file name :param timtol: time difference tolerance in days for considering data as the same timestamp :return:
