Joint Science Discussions with XRT and SOT.#

19th March 09:00

This page refers to one day of a closed meeting of the EIS consortium

Comments from attendees welcome!#

If you are attending this day of the meeting, please comment here if you would like to give input.

Those without an EISWiki account (shame on you... if you're on the team!) can mail their comments and intended contribution topics to David Williams.

It would be good to have a discussion about this agenda before the meeting, here on the EISWiki.

Format#

At this meeting, there will be additional attendance by invitees from XRT and SOT.

Objective#

What did we discover were thorny science questions in the EIS Science session?

The main point of this day session is to construct some observing programmes to conquer(!?) these questions using information from the EIS, SOT and XRT participants at this meeting.

SOT & XRT Primers#

Most people attending this session will be familiar with the kind of physics that the post-launch EIS offers information on. So we thought it would be useful to have a primer on each of the other two instruments’ scientific capabilities, with the benefit of 2.5 years of experience.

XRT (Kelly Korreck)#

XRT#

XRT do have quasi-standard Flare mode is operational the Automatic region selection: can read the patrol images which are interleaved.

Takes about a day to create a new programme. QL images are available within a day. Would want people to check those images L0 data takes about a week to be

PRY: do the QL images go on the web? KK: Not sure, but don't think so. Maybe they could.

• Data availability

5 sites available to find the L0 data. can also use XRT_CAT (analogous to TRACE_CAT). Or ask an XRT Team member to be a co-author and

KPD: is there an explanation of XRT_CAT KK: XAG.pdf is in SSW and on the SAO webpage. Also have a file from the Paris workshop to show how

HEM: is it updated a lot? KK: XRT_PREP is, but the analysis process isn't much different. HEM: but the analysis guide KK: There is someone tasked with providing the new version of the filter ratio programmes.

READ_XRT creates SSW-style index-data pairs. Then run XRT_PREP on that. There's been a lot of work on that. Documentation is in the IDL software headers.

• Temperature analysis

At least 6 different filters needed to do DEM analysis with multi-filter sets. No software yet to make movies.

JI: is there a synoptic daily temperature map? KK: Not yet. Maybe Narukage has the way to do that.

• Co-alignment

This is still an open issue. HEM: How accurate is the header information.

• Effects on-orbit
  • From Dec 2006 to Jan 2007, don't trust the header information: it's all Al_Poly.
  • absorption layer is decreasing response (make_xrt_wave_resp). This is a time-dependent absorption function. So it's a fairly sticky bit of correction. There was a hope of coming up with a photometric correction. There's nothing in the software
  • spot-like contamination -- can remove this with xrt_tup_comtam. This does a simple averaging. Another to be released soon does gradient fits iteratively. The attenuation isn't 100%, though, so you can recover the contrast in those areas in many cases, with AR signal levels.
  • cross-calibration with EIS, etc. May be a bone of contention?
  • Co-alignment
  • ...

TWo lists can be joined: xrt_science -- discussion of science xrt_users -- for end-users to provide support for one another.

KPD: one of the things I'd like to have are movies or time-sequences from a single filter or single exposure times. Can you make them with XRT_CAT? KK: There's no standard EDL: XRT_CAT, WHERE on filter wheel.

• XBPs

missed this part due to editor's prerogative

• Sheared field in ARs through morphology.

• DEM intro:

Need 6 or 7 different filters to do this. Reeves broke the DEM up into images into different temperatures. Can EIS be used to check some of this data. Helen and Kathy might wish to work onthis. Could we somehow make a filter respons for EIS.

• Flare shrinking loops through morphology

• Sigmoid structures

Addressing Our Major Science Goals#

Discussion Session Having talked about 1. the science issues we think are outstanding for EIS, (previous day) 2. what SOT and XRT can offer in terms of physical observations, we need to marry these and work out what co-observations we all want in order to address our major science goals.
