CIFBuild

Back to Calibration Homepage

Using cifbuild

With the following form you can interact with the SAS task cifbuild. Only two parameters of that task are of relevance here: the observation date and the analysis date. Both have the following format: yyyy-mm-ddThh:mm:ss. The string now is also a valid date.

The observation date is available in sereval places, one of these is in the ODF constituent rrrr_oooooooooo_SCX00000SUM.ASC. For example:

OBSERVATION
0092970701 / Observation/Slew Identifier
0269 / Revolution number
2001-05-29T17:16:58 / Scheduled Start Time   <-- Use this date
2001-05-29T20:47:05 / Scheduled Stop Time

The analysis date will in general be now, but can also be any other date. You should read the documentation of the task cifbuild for more details.

Observation date:		[yyyy-mm-ddThh:mm:ss]
Analysis date:		[yyyy-mm-ddThh:mm:ss]

Note: do not enter an analysis date earlier than 2000-12-01, as the calibration database is known not to be complete before then. This condition is not yet checked for in the form.

Options

1.		Allow me to download the CIF
		This will create a CIF based on the two dates above. You'll be allowed to ftp the resulting CIF to your machine.
2.		Prepare a script to ftp all the CCF constituents
		This will generate a (Unix/Linux) shell script with which you can download via ftp all the CCF constituents in the CIF. You must copy the script from the browser into a file, edit the password field, make that file executable, and run it in the directory where you want to download the CCF constituents.
3.		Compare with my CIF
		My CIF is:
		This will compare a CIF you upload with the CIF generated above. You'll then be able to download the CCF constituents that are not in your CIF, but only if you ahve also selected one of the download options above.
4.		Allow me to download the individual CCF constituents
		This will generate a list of ftp links to the individual CCF constituents.

Problems ?

Questions regarding the CCF should be addressed to the XMM-Newton Helpdesk.
