epic4 Configuration and Administration Guide

Routine EPIC duties

There are a number of routine tasks related to EPIC, mainly in retrieving calibration data and

housekeeping (SPEVAL) files.

Calibration data

Approximately once a week, I receive an email notification from Michael Kirsch

([email protected]

) of new cal closed data. This data I manually transfer to epic4 by

ftp, into a staging directory /xmm/archive/flight/orbits/latest before unpacking into the

/xmm/archive/flights/orbits directory. Softlinks to the data are created in

/xmm/current/flight/calve/orbits.

Though this is a manual operation, the steps are always the same and boil down to little more

than half a dozen commands or so. A cal closed download and unpacking session is shown

below. There is no need to be the root user to do this – any regular user can follow this

procedure. User input is highlighted in blue.

Note that the username and password to use at the Vilspa FTP prompt is:

Username: epic_ex

Password: 20epic_ex02

> cd /xmm/archive/flight/

> ftp xmm.vilspa.esa.es

In this session, we see that there is only one observation available, with observation ID

0147800201. However, with the ftp command mget (having first turned prompts off with the

prompt command) all gzipped observations can be downloaded unattended. If there are many

observations to download, this can take some time.
