+ | From this page you can download the drizzling software library, **drizzlib**, which reprojects data from HEALPix to local WCS FITS format. The current library is available in Python3. Older versions in Python2 are available, but no longer actively maintained. | ||
The drizzling library uses a strategy where the surface of pixel intersection is computed as presented in Appendix A of Paradis et al., 2012, A&A, 543, 103. This method allows fast ingestion and guarantees the photometric accuracy of the transformation with minimal data loss during the transformation from HEALPix to local WCS FITS. | The drizzling library uses a strategy where the surface of pixel intersection is computed as presented in Appendix A of Paradis et al., 2012, A&A, 543, 103.
