Content of a Project Account

At your first login, the project account named x007 contains the following subdirectories:

reports: It contains all the pre-calibration performed by the Astronomer on Duty (AoD) on the site. This subdirectory is in read access only. For a given observing date, you should find the following compressed files:

28-feb-2001-x007.hpb.gz: the header file containing the calibration curves of the data.
28-feb-2001-x007.ps.gz: the postscript file containing the result of this calibration. This file should be carefully read before starting a new calibration.
show-28-feb-2001-x007.ps.gz: the postscript file corresponding to a first look of the data. It includes meteo conditions (wind, mm of water, system temperature) but also pointing and focus errors. In many cases, this file can help to interpret dubious data. This file should also be read carefully before starting calibration.
The file x007.note are notes written by the AoD on the site. This file is updated at each period of observations. It gives important informations about the data quality and possible problems.

headers: It initially contains a copy of reports. Files should be uncompressed and data calibration should be performed in this subdirectory. This is the default directory of CLIC. However before activating CLIC, it is better to move to this subdirectory using the kshell command: ``$cd ~/headers''.
maps: This subdirectory, empty at the beginning, should contain at the end all the UVT tables and the maps produced. Using the CLIC procedure ``Write_A_UV_Table'', the UVT tables are created by default in this directory which is also the default directory for GRAPHIC and MAPPING.
tmp/DATA: This subdirectory contains the raw data files (IPB) and their corresponding log files. In the example presented above, it would be: H228X007.IPB, H228X007.OBS, H228X007.RDI. Access to this directory and to the raw data files is automatically handled by CLIC.
DATA: Most of the time this directory is empty. However, it can contain some IPB files and their corresponding log files. Like in the case of tmp/DATA, its use is transparent. The reducer does not need to know the exact location of the raw data files on her/his account. CLIC handles it for him/her.

Note that only the subdirectories reports, headers and maps are saved on CDroms by the automatic procedure.
