______________________THE INTENT OF THIS EXPLODER__________________________
1a) What is the ROSATCALDB Exploder intended/used for ?
-------------------------------------------------------
... The ROSATCALDB exploder is primarily intended to distribute information
regarding calibration files/software to "managers" of Calibration Databases
(CALDBs) other than at the OGIP.
... This information consists of:
- updates/instructions regarding maintenence of a CALDB
- updates & big fixes the the CALDB access software
- new ROSAT files added to the OGIP CALDB.
- discoveries/rumours of corrupt/incorrect ROSAT files in the OGIP CALDB
... "Managers" of CALDBs are free to pass the information onto their
user community as they see fit.
1b) What is it's relationship with other ROSAT-related Exploders ?
------------------------------------------------------------------
... The information posted on the ROSATCALDB exploder IS NOT intended
to replace the information distributed by the ROSAT project or GOFs. As
such it should not be necessary for all Principal Investigators and
Co-Investigators to subscribe to the ROSATCALDB exploder. Information that
all PIs/Co-Is need to be informed of will be officially distributed by the
ROSAT project/GOF vai the appropriate means.

2a) Who is allowed to be a recipient ?
--------------------------------------
... This exploder is open to.
... However, to repeat 1a) & 1b), it is primarily intended for "managers" of
CALDBs are remote sites. Thus, potential subscribers may be querried as to
whether they fully understand the intent to the exploder (empasizing that
the primary source of calibration information for the general GO/Co-I is
the project/GOFs).
... Subscribers who 'abuse' the system may be removed.
(Those of you who recieve this message via e-mail are already subscribers)
2b) Who can post messages ?
---------------------------
... Only OGIP Calibration Database (Caldb) personel are currently allowed
to post messages to the ROSATCALDB exploder. This is primarily to keep
the traffic on the exploder to a reasonable minimum of "official CALDB"
postings, and to channel questions directly to the most appropriate
people.
... General question/comments regarding
- the contents/software of the OGIP Caldb should be addressed to:
Ian M George <george@lheavx.gsfc.nasa.gov>
- the ROSAT mission, the onboard instruments, and the extraction/analysis
of data therefrom should be addressed to:
ROSAT Help Desk <rosat@rosserv.gsfc.nasa.gov>
2c) Who are the other recipients ?
----------------------------------
... Here is the current list of non-concealed subscribers:
ANDRE@UNI-SW.GWDG.DE Avanteeseling

2d) Should/can I subscribe ?
----------------------------
(Those of you who recieve this message via e-mail are already subscribers)
... You *should* subscribe if you are responsible for setting up and
maintaining a copy of the OGIP CALDB for ROSAT are your site. If this is
the case, then you will be what the OGIP refers to as a "remote CALDB
manager".
... You may *wish* to subscribe if you are a PI/Co-I working on ROSAT data
using OGIP-supplied FTOOLS/XSELECT, and feel you want to keep up-to-date
of new calibration files/software available from the OGIP.
HOWEVER, before subscribing consider the following:
- all significant information will in any case be "officially"
distributed to all PI/Co-Is by the project/GOFs,
- your mail box may be cluttered with irrelevant/boring messages
- all significant posts on this exploder are flaged on the OGIP
CALDB's "Whats New" page on the WWW; URL:
http://heasarc.gsfc.nasa.gov/docs/heasarc/caldb/caldb_wotsnew.html
- there is an archive of all the traffic on this exploder available
online via the WWW; URL:
http://heasarc.gsfc.nasa.gov/listserv/rosatcaldb/maillist.html
2e) How do I subscribe ?
------------------------
(Those of you who recieve this message via e-mail are already subscribers)
... If you indeed decide that you wish to subscribe to the ROSAT CALDB
exploder, simply e-mail:
listserv@athena.gsfc.nasa.gov
with the main text (NOT the subject) of the message containing
subscribe rosatcaldb {your name}
where {your name} is your real name (eg: A.Einstein).
... Help on other features of the listserv software (some of which can be
applied to the ROSATCALDB exploder/archive) can be obtained by e-mailing:
listserv@athena.gsfc.nasa.gov
with the text (NOT the subject) of the message containing the word help.
2f) How do I get off this exploder ?!
----------------------------------------------
... If you have subscribed to ROSATCALDB, but now wish to remove yourself
from the exploder, simply e-mail:
listserv@athena.gsfc.nasa.gov
with the main text (NOT the subject) of the message containing
unsubscribe rosatcaldb
NOTE: This mail message should be sent from the same e-mail address as that
to which ROSATCALDB messages were formerly being sent.
____________________THE TRAFIC ON THIS EXPLODER_________________________
3a) What are the messages about ?
---------------------------------
... As stated in 1a), the ROSATCALDB exploder is primarily intended to
distribute information regarding calibration files/software to "managers" of
Calibration Databases (CALDBs) other than at the OGIP.
... This information consists of:
- updates/instructions regarding maintenence of a CALDB
- updates & big fixes the the CALDB access software
- new ROSAT files added to the OGIP CALDB.
- discoveries/rumours of corrupt/incorrect ROSAT files in the OGIP CALDB
... "Managers" of CALDBs are free to pass the information onto their
user community as they see fit.
3b) How often/many messages are posted ?
----------------------------------------
... The traffic on this exploder is usually very small
- approximately 1 or 2 messages per month
3c) How Reliable/Informative are they ?
---------------------------------------
... The majority of messages over the last year have simply been intended
to inform "remote CALDB managers" of new ROSAT calibration datasets.
Thus they have merely reported the location of the new files and whether
and now these new datasets relate to pre-existing datasets. In cases
where the new datasets supercede a pre-existing dataset, information
is also supplied on what action should be taken by remote CALDB managers
to update their local CIFs.
3d) On whose Authority are they posted ?
----------------------------------------
... The messages are usually constructed solely by the OGIP CALDB staff.
However, obviously they are constructed in close collaboration with
the author/GOF when necessary.
