Haslam 408Mhz reprocessed survey collection

Remazeilles et al. 2014 have re-evaluated and re-processed the rawest Haslam 408 MHz data, available from the Max Planck Institute for Radioastronomy Survey Sampler website, to produce an improved source-subtracted and destriped 408 MHz all-sky map. Large-scale striations associated with correlated low-frequency noise in the scan direction are reduced using a Fourier-based filtering technique. The most important improvement results from the removal of extra-galactic sources. An iterative combination of two techniques - two-dimensional Gaussian fitting and minimum curvature spline surface inpainting - are used to remove the brightest sources (with flux density larger than 2 Jy).Desources destrier map.Original acknowledgement for data: see Remazeilles et al.
