eimagecombine (eimagecombine-0.9) [xmmsas_20211130_0941-20.0.0]


The meta-task eimagecombine combines the individual output images from the task eimageget to produce a background-subtracted, vignetting-corrected, and smoothed image of EPIC exposures.

eimagecombine uses all images, which are found in the directory the script is executed in and follow the naming convention of the output of eimageget. Note that alternatively the file-name extension “.fits.gz” is allowed to enable the usage of compressed input images. Compression becomes very efficient for larger mosaic images. In the case of existence of both files, the uncompressed file will be used.

The script can be started and interrupted at several steps. In this case, the user must ensure that the output files of the previous steps were created properly and not removed (keepinterstage=1).

The task operates as follows:
