Remove template.fits #61

Closed mzechmeister closed 4 months ago

mzechmeister commented 8 months ago

The template.fits (*.tpl.fits) is a tabulation of the spline model with an oversampling by a factor of about four. It is a relict of previous coadding methods. This leads to confusion and should be removed. Some refactoring will be needed. Just storing the knot values (or the B-spline amplitudes) is really sufficient.

Instructions or a script, how the get the spline model, should be given.

The storing the flux as float32 should be also sufficient and will further reduce the size of serval output.

Solved with c2f47b2. See also associated issues in #63.

A tutorial how to reconstruct the spline from the fits file is given in https://gist.github.com/mzechmeister/eac1b83a7d5cdc64c149fafd959adca8
