### Question:
SLCImage { public double computeDeltaRange(double pixel) { return mlRg * (pix2range(pixel + 1) - pix2range(pixel)); } SLCImage();  SLCImage(MetadataElement element); void parseResFile(File resFileName); double pix2tr(double pixel); double pix2range(double pixel); double tr2pix(double rangeTime); double line2ta(double line); double ta2line(double azitime); Point lp2t(Point p); double getRadarWavelength(); Point getApproxRadarCentreOriginal(); GeoPos getApproxGeoCentreOriginal(); Point getApproxXYZCentreOriginal(); Window getCurrentWindow(); double getPRF(); double getAzimuthBandwidth(); int getCoarseOffsetP(); double gettRange1(); void settRange1(double tRange1); double getRangeBandwidth(); void setRangeBandwidth(double rangeBandwidth); double getRsr2x(); void setRsr2x(double rsr2x); void setCoarseOffsetP(int offsetP); void setCoarseOffsetL(int offsetL); int getMlAz(); void setMlAz(int mlAz); int getMlRg(); void setMlRg(int mlRg); double getMjd(); long getOrbitNumber(); double computeDeltaRange(double pixel); double computeDeltaRange(Point sarPixel); double computeRangeResolution(double pixel); double computeRangeResolution(Point sarPixel); public Doppler doppler; }### Answer:
@Test public void testComputeDeltaRange() throws Exception { Assert.assertEquals(deltaRange_EXPECTED, master.computeDeltaRange(CORNER_REFLECTOR_4), eps05); }
