XRT Level0 data Mpeg Movie Archive
This web site provides movies of XRT level0 data (data category for
uncalibrated data) organized by month.
The aim of this service is to provide users of XRT data a quick method
to check data availability and quality before accessing the actual data
archive.
To access the movies, select the year and month
from the navigation bar on the left.
Specifications of our movies are as follows.
- - Movies are provided in mpeg-4 format and created using the ffmpeg
software.
- - Movie files are created for each filter pair and for certain time
periods ranging from 3 days to the whole month depending on the data volume
obtained for that month.
- - The movies are scaled using a red and white reversed color table
with log intensity to see faint structures better.
- - Movies are created for two different field of views (FOVs):
- * partial frames with 512"x512" and smaller.
- * partial frames larger than 512"x512" and full frame readouts.
- - The pointing information is corrected for using the co-alignment
database that is applied in XRT_PREP.
- - Images NOT included in the movie:
- * Dark frames.
- * Images with the G-band filter.
- * Flare Detection Images (8x8 binning full frame readouts).
- To avoid severe flickering, the shorter exposure images of long/short
paired observations are extracted to a separate file labeled
with '_Short' (when successfully detected).
Here are examples of movie file name
