solppraw — format raw Solstice results into human readable text

solppraw [file]

solppraw reads the solstice(1) outputs from file or from standard input whether a filename is provided as an argument or not, respectively. For each simulated sun direction, it formats the raw results into a human readable text file, simplifying the analysis of the results.

The naming scheme for the output files depends on the way the sun direction was provided to solstice(1):

  • using the -D azimuth,elevation flag: the output file is named after the following pattern: 
    printf "%g-%g-raw-results.txt" azimuth elevation
  • using the -L latitude,longitude and -T time flags: the output file is named after the following pattern: 
    printf "%g-%g-%s-results.txt" latitude longitude time

The solppraw utility exits 0 on success, and >0 if an error occurs.

Invoke solstice(1) to simulate two sun directions and pipe the results directly to solppraw, without any intermediary file:

solstice -D45,70 -D50,75 -R rcvs.yaml input.yaml | solppraw

Alternatively, invoke solstice(1) to simulate a sun direction and write the results to the output file, then post-process it with solppraw:

solstice -L3,40 -T"2026-08-15T17:20:00" -R rcvs.yaml -o output input.yaml
solppraw output

solmaps(1), solpaths(1), solpp(1), solstice(1), solstice-output(5)

solppraw was initially developed with funding from the (Laboratory of Excellence), in collaboration with the PROMES Laboratory of the French National Centre for Scientific Research (CNRS). Starting in 2026, a new development effort funded by Ademe is ongoing.
