V & V help and links

This page is intended to provide helpful links to someone learning the V & V process

Read the general V&V help page first. Below is a summary, but far from all-inclusive.

Before you can start

Obtain the v & v username and password and apply for an archive password.

The first time

Log on to proteus.cfa.harvard.edu using ssh. (ssh proteus.cfa.harvard.edu -l vvops)
Set up a working directory on /data/vv

Every time

Log on to Proteus.

Run setascds (type setascds from the command line)
This will initialize ciao and the perl scripts used for V&V

If the data is recent it will be located in the cache. The directory will be in the alert
Location of data in cache -> /dsops/ap/sdp.9/cache/2003_08_09

Symlink all files containing the obsid to somewhere in your working directory.
V&V>ln -s /dsops/ap/sdp.9/cache/2003_08_09/[acis,hrc]/OBSID .
V&V>ln -s /dsops/ap/sdp.9/cache/2003_08_09/obi/OBSID .
(see staff/dph/vv_prep.csh)
If the data is older (~10+ days) it will need to be retrieved from the archive
V&V>getarc.csh username OBSID retrieve standard

Aspect plots and log

Locate the aspect plot and log with
V&V>ls /dsops/current/VV_AP/[acis,hrc]*OBSID*

Look at the tail end of the log for aspect problems.
View the .ps aspect plot.
More info on aspect plots.

View information on observation

Verify target location

Run vv_perl.pl

Grating observations

Inspect the pha spectrum (explained on the general V&V help page)

Run osort_image.

When Done

Submit V & V report.
V&V>vv_submit.pl OBSID
