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.
