Arrow Datasets
Here we are going to see how to work with the R arrow package to make a CSV and Parquet backed database, strictly an arrow Dataset. This allows for larger than memory processing of data that is big enough to bit on your RAID array, but too big to safely process in RAM (you as standard need no less than x2 the size of the object to do anything oth...

ProSpect: Filter Transforms
Filter Transforms Aaron Robotham 2020-04-20 In astronomy we often have filters that are similar but annoyingly different to each other. For instance the Sloan \(ugri\) filter set are all similar to, but not identical to, the VST \(ugri\) filters. In fact in detail probably almost no two telescopes have identical versions of the same filters (even ...

ProSpect: Extra Galactic Background Light
Extra Galactic Background Light Aaron Robotham 2020-01-15 The Extra Galactic Background Light (EBL) is the flux density observed across all wavelengths of light. It is dominated by the CMB, followed by the optical and NIR (about 10-20%). There are a few ways to measure it, but my work has focussed on the method of integrating out the number counts...

ProFit: Found 2 Fit
ProFit: Found 2 Fit Aaron Robotham 2021-02-23 In this vignette we will demonstrate fitting in the most automated mode available in ProFit. This is very high level, but hopefully usefully so in many cases. Users who need finer level control should look at some of the other vignettes that break various phases we do automatically here into more manua...
