double chat(double x)
Calculate Bracewell's "Chinese hat" function: chat(x) = 0.5*(acos(x)-abs(x)*sqrt(1-x*x)) This is t...
double jinc(double x)
Calculates the "jinc" function which is J1(x)/x, where J1(x) is the Bessel function of the first kind...
double pchat(double x)
Polynomial approximation to Bracewell's Chinese hat function, from MIRIAD.
double bracewellJinc(double x)
Bracewell's jinc function = J1(pi*x)/(2*x)
