MetaCurve is a tool for extracting lightcurves from video files or FITS sequences.
It is unique in handling 12-bit .SER format output by LucamRecorder using digital video cameras such as Lumenera.
MetaCurve strives to be interactive, easy to use, and hard for the user to make a mistake. It aims to generate a raw, linear lightcurve of an event such as an occultation.
It also handles .AVI files and sequences of FITS files.
- Easy to use and hard to make a mistake
- Highly interactive, with zooming, panning and display gamma to study the video in detail
- Aligns and stacks 30 frames with the push of a button, to reveal faint stars
- Displays intensities in fundamental units of magnitude and electrons
- Finds the gamma of your video camera and linearizes your data
- Displays the magnitude and SNR of stars with a mouse click
- Works with normal .AVI files, 8 or 12-bit .SER files, and 16 or 32-bit FITS sequences
- Outputs a detailed log including magnitude, SNR, and more
- Load video
- Shift-Click on some reference stars with the mouse
- Click "Avg 30 frames" to generate a clean, stacked view revealing faint stars
- Add the occulted star
- Press SetRef to lock the position of the faint star
- Right click at two different frames to enter the exact time of those frames
- Press RecLog to generate a log with all times indicated
