Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...

... Specs . ... Data in folding and search modes will be output as FITS files. The DFB also has a mode that provides digitized baseband output suitable for the next generation of real-time coherent dedispersion systems. ... The output file will be a standard, pulsar folded profile with full polarisation and a given number of phase bins, frequency channels and subintegrations. ... The DFB is specified to allow 2048 frequency channels and 2048 phase bins for a 4-ms pulsar recorded with 8-bit sampling. ...

... Archives . ... In the XSPEC packages, the parametric bootstrap is command FAKEIT, which makes Monte Carlo simulation of specified spectral model. XSPEC does not provide a nonparametric bootstrap capability. Parametric Bootstrap: $$X_1^*,?, X_n^* \sim F(\cdot;\theta_n)$$ . Both $$\sqrt{n} \sup_x |F_n(x)-F(x;\theta_n)|$$ and $$\sqrt{n} \sup_x |F_n^*(x)-F(x;\theta_n^*)|$$ have the same limiting distribution. ... Nonparametric Bootstrap: $$X_1^*,?, ...
