Due to the finite width of the point spread function (PSF) of the Yohkoh Soft X-Ray Telescope (SXT) mirror, a certain amount of blurring effect is inevitable in the observed soft X-ray images.
First, we take the envelope function of the 5 Hz high-pass-filtered seismogram, smooth it by the half width of 50 point, and stack the resulting three-component envelopes to obtain the envelope function for each station.
An approximation is given by (convolution of a Gaussian object with a Gaussian PSF) where ρ PSF is the width of the point spread function and ρ(p) is our final estimate of the radius of p. Our final estimate is within 1% of the true value when tested against beads with a diameter of 1100 nm injected into the embryo.
Ideally, each line should be 1 mm (about 1/32 inch) apart, or at least as close as the width of the point of your marker will allow.
The remaining bit widths, such as the fractional bit width of fixed-point, and the mantissa bit width of floating-point numbers, are predominantly related to the precision of the calculation.
As discussed in Section 3.1, based on the range information, we are able to determine the integer bit width of fixed-point, and partly determine the exponent bit width of floating-point numbers (as exponent bit width does not only relate to the range but also to the accuracy).
Based on their values, the integer bit width of fixed-point numbers can be determined.
Using both the minimum and maximum values, the exponent bit width of floating-point numbers can be determined.
The obtained spectra are smoothed by applying the mean smoothing algorithm from the subroutine "smooth" in the Seismic Analysis Code (Goldstein et al., 2003), with half width of five points.
The obtained spectra are then smoothed by computing the mean with half width of five points using the subroutine "smooth" in the Seismic Analysis Code (Goldstein et al., 2003).
