Adding null bases to the metric

9

Is there any interest in adding null bases to the metric? This enables GA to implement euclidean spaces in projective geometry. By limiting the metric to positive and negative bases...

The product of a range and a unit should create a new range, not a vector

1

The following expression generates a vector: julia> (1:3)*seconds 3-element Vector{AstroPeriod{AstroTime.Periods.Second, Float64}}: 1.0 seconds 2.0 seconds 3.0 seconds I argue that it should create a new range: julia> (1:3)*seconds 1 seconds:...

gtltcube run is too long.

It takes gtltcube >4 hours to process 15 years of Fermi data (~2 GB), while all other processes take

Distinguishing between statistical and systematic errors in Measurements.jl

1

Measurements.jl implicitly assumes that all errors are statistical errors. In most cases this is correct. However, there are cases when the total error is a combination of statistical and systematic...

I refer you to Chapter 3 of the Explanatory Supplement to the Astronomical Almanac entitled "Celestial Reference Systems". This chapter shows that the sky coords implemented in this package are...

The Bretthorst algorithm is a fully Bayesian derivation of the Schuster/Lomb periodogram or which Lomb-Scargle is a variant. In my experience the Bretthorst algorithm does a better job at suppressing...
