Welcome to the EOVSA data products documentation. EOVSA observes the full disk of the Sun at all times when the Sun is >10 degrees above the local horizon, which is season dependent and ranges from 7-12 hours duration centered on 20 UT. During January, coverage will be 16-24 UT daily, 7 days/week. EOVSA will provide microwave spectra and imaging at up to 451 frequencies between 1 and 18 GHz. We deliver the radio interferometry data in level 0-2.

Data Definition

Level 0 - Raw visibility data from the instrument

Level 1 - Calibrated visibility data

Level 1 data have all of the required content to produce Level 2 data products

CASA 1-min averaged ms

CASA Event ms

Level 2 - Images and spectrogram data in standard FITS format

All-day TP spectrum

Daily total power full-Sun-integrated spectrogram calibrated in solar flux units are provided at 451 frequencies and 1 s time resolution.

All-day XP spectrum

Daily cross power spectrogram (mean flux from baselines with "intermediate" lengths) calibrated in solar flux units are provided at 451 frequencies and 1 s time resolution. XP spectrogram has much better sensitivity to weak bursts.

Synoptic 6-band Images

Full disk images at 6 selected frequency bands centered at 1.4, 3.0, 4.5, 6.8, 10.2, and 13.9 GHz are provided once per day, calibrated in brightness temperature.
