Figure 4
Measurement boxes with parameters NX = NY = 23, NRX = 5, NRY = 4 and NC = 11 used for the integration of spots on corrected images as presented in Tables 3 and 4, displayed over an image from each ensemble of corrected images. (a) In zone A, the measurement box central pixel is X = Y = 306 pixels. (b) In zone B, the centroid of the spot has been shifted in both X and Y by six pixels, such that the centre of the measurement box is at X = Y = 300 pixels. |
