EOVSA Data products
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.
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 Event ms
Level 2 - Images and spectrogram data in standard FITS format
Daily total power full-Sun-integrated spectrogram calibrated in solar flux units are provided at 451 frequencies and 1 s time resolution.
from suncasa.eovsa import eovsa_dspec as ds ## define the dynamic spectrum file. tpfits = 'EOVSA_TPall_20191225.fts' ## display the dynamic spectrum. ds.dspec(tpfits)
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.
<syntaxhighlight lang="python"> from suncasa.eovsa import eovsa_dspec as ds
- define the dynamic spectrum file.
tpfits = 'EOVSA_XPall_20191225.fts'
- display the dynamic spectrum.
