Apply BV / BVR / UBV / UBVR photometric transformation coefficients to AAVSO Extended Format observations. Generates a light curve and exports a submission-ready file.
Compute altitude curves, rise/set times, and target window for any variable star. Fetches the latest AAVSO observations and plots twilight, astronomical darkness, and culmination.
Inspect loaded photometric data and run Lomb-Scargle period analysis on the selected filter. Generates a light curve, periodogram, and phased light-curve products for local download.
Converts AstroImageJ photometry tables (.tbl) into AAVSO Extended File Format (.txt), ready for WebObs submission. A light-curve PNG is generated automatically alongside the report.
