multixmmselect (xmmselect-2.67) [xmmsas_20211130_0941-20.0.0]


Product extraction

As mentioned above, the Filtered Table,Fix Expression,buttonHistogram, OGIP spectrum buttons are disabled in the multixmmselect task. Only Image, OGIP Rate Curve, and OGIP Spectral Products are enabled.

Pushing either of these will trigger the following actions:

  1. Execution of evselect with the selection expression in the top expression entry field. Before evselect is actually executed, its parameter dialog is presented to give the user full control over the product extraction process, i.e., all of evselect's parameters (e.g. bin size for rates curve extraction, name of output data set, etc.) can be altered (e.g. bin size for rate curve extraction, name of output data set, etc.).
  2. Accumulation of the respective product with a default name
  3. Except for event lists, execution of a product displayer (either dsplot or imgdisplay) with the name of the generated product

A prerequisite to the extraction of images, and rate curves is the selection of data set columns which define the primary product axes (see above), in the case of multixmmselect only (X,Y) are allowed to create the EPIC mosaic image. See the xmmselect task documentation for a detailed explanation of the product extraction generation.
