What I did during my XRT DV week in Nov-2014

Summary of my Hinode/XRT Data Verification duty week in 14-21 Nov, 2014

(by Aki Takeda, 2, December 2014)

1. Creation of the 15-Nov Flare movie.

An ejection was observed, associated with the M3.2 flare from AR12209.

2014/11/15 11:40 --  12:10   GOES class M3.2, AR12209. <---  
2014/11/15 20:38 --  20:50              M3.7  AR12209.

Since it was Hinode's target region, the flare was observed with some pre-flare buffer images. I gave it a try to create a flare movie with the best co-alignment effort using Keiji's database available for the level0 data.

Use of Keiji's co-alignment database

comparison of coalignment movies Movie for XPOW

[caption of the movie]
The images are co-aligned so that all the images in a sequence have the same value of index.xcen and index.ycen (the first image was chosen to the reference).
Left images: co-aligned besed only on the the original FITS header information without using the co-alignment DataBase.
Middle images: co-aligned using the co-alignment DB, with default setting (UFSS besed DB).
Right images: co-aligned using the co-alignment DB, with the AIA_CC keyword (AIA image based DB).

[comments on the movie]

the coordinate values are improved in DB-corrected images (middle & right images).
the erroneous records in the original FITS header (No. 62 image) were corrected in the co-alignment DB.
Don't trust the co-alignment by PLOT_MAP, which does not handle sub-pixel level. Shift image before making maps with INDEX2MAP. comparison movie
for the co-alignment only among XRT images, the UFSS based DB works better, while the AIA based DB works better for the co-alignment with other instruments.

[Bonus] LASCO/C2 movie for early Nov., 2014

2. Optimization of the 9-filter synoptics sequence.

Example of 9-filter synoptics

The latest XOB as of 28-Nov-2014 : #1A63

No more take C-poly pair (so now 8-filter synoptics!).
Al-poly/Ti-poly single --> double (250ms/2.0sec)
Med-Al single --> double (5.7sec/32sec)
Keep taking Thick-Be images (64 sec)

Now the total duration of the XOB is 6:55 sec, enough time left for the pointing change after regular synoptics (10 min).

[UPDATE] Although COT simulates the duration of the XOB#1A63 is 6:55, the actual data shows that it takes 7:20 to run through.

Med-Al doublet (5.7sec/32sec --> 4.0sec/23sec)

The latest XOB as of 3-Dec-2014 : #1A65. Now the simulated duration is 6:32, hopefully finish within 7 min in the actual sequence.

3. Prepare new flare response. --- The "Wave Quest" version.

SXT flare response for the 3-Mar-2000 M3.8 flare.

New XRT flare response since 22-Nov-2014.

2007 analysis by N. Narukage and SXT new responses.
