Check if there is a time shift in triangle method
There may be an overall time shift in the triangle method that is only apparent when run at long sample intervals and when compared to the full method. Please check if this is the case. The likely fix is in this line: https://code.usgs.gov/ghsc/lhp/lsforce/-/blob/master/lsforce/lsforce.py#L553
I believe this line should be changed from:
self.T0 = -2 * self.triangle_half_width # [s] Double the half-width
to
self.T0 = -self.triangle_half_width
but this needs verification.
