This page is intended to allow distribution and progress updates on the rechecking of Marc's Q=2 redshifts.

There are 11 250-object subsets of the data to be rechecked.  Please edit the table below to reflect sections you are checking.

===== Instructions: =====



==== 1) ====
 You'll need to have cvs and the IDL directory structure set up on the machine you'll be working on (along with a copy of IDL, of course!).  Step-by-step instructions are here:
\\
http://deep.berkeley.edu/private/using_cvs\\
\\
This should give you the latest version of zspec_list, among other things.  Note that the code will need to be in your IDL path, and the D2_RESULTS directory (generally set in your .idlenv file) needs to point to the appropriate place; e.g.
\\
''setenv D2_RESULTS	~/deep2/d2_results''
\\
on my computer.

If you don't have a .idlenv file loaded in your .cshrc (or .bashrc), be sure to add the required commands to your .cshrc (or .bashrc).


D2_RESULTS should be a new directory, unless you've set it up before; it's where the files you'll look at will be put.


==== 2) ====
 You need to download all the zresults files.  Open a new window, and do:
\\
''cd $D2_RESULTS\\
pwd\\
rsync -uarvL %%--%%rsh=%%"%%ssh%%"%% deepteam@lupus.berkeley.edu:/deep2/marc/d2_data/v1_1/zresult .\\
''
\\
Make sure that the pwd command tells you that you're in the directory you set $D2_RESULTS to in your .idlenv before issuing the rsync command.  Ask Nick or Michael for the deepteam password (or anyone else who knows it).


==== 3) ====
 Choose an unclaimed set on this page, and add your name next to it.

Then:



== a) ==
 get rid of any old set to make room.

issue the commands at a UNIX prompt:\\ 
\\
''cd $D2_RESULTS \\
rm %%-%%rf  */*/sl* \\
rm %%-%%rf */*/spec* \\
''

== b) ==
 download your new set.

 issue the commands at a UNIX prompt:\\
\\
''cd $D2_RESULTS \\
rsync %%-%%uarvL %%--%%include %%"*recheck*_X.*"%% %%--%%exclude %%"*.*"%% %%--rsh="ssh"%% deepteam@lupus.berkeley.edu:/deepscr0/jnewman/recheck/ . \\
rsync %%-%%uarvL %%--%%rsh=%%"ssh"%% deepteam@lupus.berkeley.edu:/deepscr0/jnewman/recheck/files_X/ . \\
''
where X is 0,1,... 10 --- whatever the number of your set is.


== c) ==
 start IDL, and run zspec_list :\\
\\
''IDL> zstructs%%=%%mrdfits(%%'zrecheck_X.fits'%%,1) \\
''
where X is 0,1,...10\\
\\
''IDL> zspec_list,zstructs \\
''

When you find an object whose redshift/quality/comment you want to change, edit the corresponding line in the file redshifts_recheck_X.txt .  The file should contain the original comments+Marc's comments, and have Marc's redshift quality.

This is a text file in the necessary format for modifying the zcat.  You probably want to do a search-and-replace to change 'marc' to your own username before editing.  

e.g. (at a UNIX prompt):\\
\\
''sed s/marc_rechecked/yournamehere/g redshifts_recheck_X.txt > redshifts_recheck_X_yourname.txt \\
''
\\
The redshift is the 4th column, zquality 5th, and comment is the last column.

This file should show up in your $D2_RESULTS directory if you follow the rsync commands above.
\\
When you're done, send the edited redshifts_recheck file to Michael Cooper for incorporation into the zcat.
\\
**NOTE:** in some cases, zspec_list may not automatically show a template fit for Marc's redshift choice.  In that case, redo the fit yourself with Marc's redshift and then proceed.





Estimated failure rates are 60% for Q=3 and 20% for Q=4, though that may be better for objects checked later.
