Telemetry from the Swift Observatory is transmitted to the Malindi Ground Station (MGS) during the short intervals when the satellite is in view of the station. The data are then transferred to the Mission Operations Center (MOC) in Pennsylvania and then to the Swift Data Center (SDC) in GSFC. The SDC converts the telemetry into FITS files, does additional processing, and posts the files to their Quick Look (QL) web site. The time between data being produced on the observatory and the corresponding FITS files being posted on the QL web site depends on several factors, such as the time to the Malindi contact.
This page contains information about the progress in posting data from recent observations of the Swift Observatory to the QL web site. This pages reports the completeness of attitude data on the web site for each of the recent snapshots for which data have been received at the MOC. A snapshot is the interval between the start of two maneuvers by the spacecraft. Attitude data are a convenient proxy for the many different kinds of data produced because there should always be a complete set of attitude data for each snapshot.
The SDC will split sequences if they become too long. The new sequences will have the same target ID (the first 8 digits of the sequence number) and a segment number (the last 3 digits of the sequence number) of 256 or higher. If such sequences are found that contain data from the snapshot, they are identified in column 2.
This page is nominally updated every 4 hours and reports on snapshots up to 18 hours prior to the update.

Column 1: <sequence no.>.<processing version no.> of the snapshot
Column 2: <segment no.>.<processing version no.> of another sequence no. with the same target ID
Columns 3 thru 8: The log10 of the number of bytes in file for 6 different types of level 1 science data for the sequence (not the snapshot). The types are: BAT event, BAT survey, UVOT events, UVOT images, XRT events, XRT images.
Column 9: Start time of the sequence
Column 10: Start time of the sequence in spacecraft time (seconds)
Column 11: Duration of the snapshot (seconds)
Column 12: Sum of time gaps in the attitude data (seconds) (-1 if attitude file not found)
Column 13: Number of attitude samples (-1 if attitude file not found)
Column 14: Are there non-zero values in the RA? (yes/no)
Column 15: Were the times in the as-flown timeline verified in the attitude data?
V=verified, P=partially verified, U=unverified
P or U may indicate gaps in the telemetry.
Column 16: Target name
