Description:
Takes a
stack of 2d frames of bolometer data, usually noise images or responsivity images, and
combines them into a single cube with, if sort is enabled, an annotated time axis or an axis
based on a numeric FITS header item. This makes it easy to look at the behaviour of a
single detector as it varies with time. Not all observations include time information or
should be sorted at all and for those set SORT to false. The 3rd axis will not be a sorted axis
in that case. This can be useful for examining bolometer maps created by MAKEMAP.
Parameters:
IN = NDF (Read)
Input file(s). Files must all be 2-d and have the same
dimensions. For the SORT option to be available they must have a DATE-OBS FITS header.
MSG_FILTER = _CHAR (Read)
Control the verbosity of the application. Values can be
NONE (no messages), QUIET (minimal messages), NORMAL, VERBOSE, DEBUG or ALL.
[NORMAL]
OUT = NDF (Write)
Single output file with all the 2d images stacked into a
single observation.
SORT = _LOGICAL (Read)
Should the data be sorted into time order
(true) or left in the order given in IN (false). If the first file in IN has no date information
sorting will be disabled automatically. Default is true if date information is available.
SORTBY = _CHAR (Read)
If the data are sorted (SORT=TRUE) this parameter controls which
header item should be used to do the sorting. Options are MJD (the date) or the name of a
numeric FITS header. MJD is not allowed if no date items are present. [MJD]
Notes:
-
No special SCUBA-2 processing is applied. The assumption is simply that you have some
images that are all the same size and you want to put them into a single cube with a time
axis.
-
Variations in pixel origin are ignored. Make sure images are aligned and are the same size.
-
Useful for looking at the variations in bolometer parameters such as images created by CALCNOISE
or CALCFLAT.
