Coronal Multi-channel Polarimeter (CoMP)

FOV: 1.05 to 1.4 Rsun ; Spatial Resolution: 4.46 arcsec/pixel; Cadence: 5 sec to 1 min.
Simulated CoMP-like data can be generated with the FORWARD Model.
CoMP Intensity
CoMP Intensity
CoMP filtergrams provide calibrated coronal emission intensity in units of millionths of Bsun, where Bsun is the brightness of the solar disk.
397 1074nm images available

32 1079nm images available

CoMP Quick Inversion
CoMP QI sample
Each CoMP Quick Inversion file (one produced per day) includes the line center intensity, linear polarization and magnetic field azimuth. These three images are in one multi-image FITS file, using FITS extensions to hold multiple images (use a fits viewer that can parse these files, such as fv).

CoMP Full Inversion
CoMP Full Inv sample
Each CoMP Full Inversion file (one produced per day) includes the line center intensity, velocity, line width, B field, linear polarization, and azimuth. These six images are in one multi-image FITS file, using FITS extensions to hold multiple images (use a fits viewer that can parse these files, such as fv).
No 1074nm file available

No 1079nm file available
