Level 0.3 / Level 0.5 Data

Level 0.3 and Level 0.5 data are very similar. One could say that the Level 0.3 data is a temporary, best effort set of Level 0.5 data based on what is available at the time of computation.

In theory, after N days the Level 0.3 data will disappear from a given date and a person will only view the Level 0.5 data. The value of N is yet to be determined. It may be as low as 5 days. Essentially, Level 0.3 is intended to be "QuickLook" data, only desired by the user who needs data ASAP (as opposed to a science analyst user).

Sources for the Level 0.3/0.5 data include:

Level 0.1 data (metadata and images from the instruments)
Orbit prediction data from the GSFC Flight Dynamics Center
Attitude data from the spacecraft
Temperature and Power data from the spacecraft and instruments

Data series that feed Level 0.3/0.5 include:

sdo.*

sdo.fds
sdo.fds_orbit_ingesthist
sdo.fds_orbit_vectors (contains both helio- and geo-centric velocity) sdo.fds_orbit_vectors_sbox sdo.hk_dayfile (Prime keys – date, apid, source, also keyword source=moc. Contains all dayflies for all SDO APIDs from MOC product server) sdo.moc_fds sdo.ancillary_science_data

hmi.*

hmi.lev0 hmi.hk_dayfile

aia.*

aia.lev0 aia.hk_dayfile

Functions intended to feed the Level 0.3/0.5 data series include:

A drms module, getfdsorbit – input: time (something that is not on the original time grid, so interpolation will be necessary), coord system (also specifies helio or geo/J2000 ecliptic or something else or interpolation parameters); output: position vector and velocity vector. Make the output doubles. (Art) No need for an intermediate series with interpolated/converted data.
1. Must change the master LZP MOC server download script, mocDlLzp.csh (JSOC/proj/lev0/scripts/mocserver), to download files to /surge, and then call script to ingest into sdo.hk_dayfile.
2. The script/module to ingest into sdo.hk_dayfile must be created.
1. Needs a sdo.asdp - Contains all the ancillary science data packet information (apid 129) (Jennifer).
  1. Need to write an ingest script/module for sdo.asdp.
  2. Input to this script is sdo.hk_dayfile.
2. Need a master lev 0.3 record creation module. It calls modules like getfdsorbit.
