ii_shadow_ubc

ii_shadow_ubc reads all raw detector, and corresponding efficiency, shadowgrams, and fills the detector dead zones. ii_shadow_ubc is run in three cases; to produce images, spectra and lightcurves. In the imaging case, for each pair of detector-efficiency shadowgrams it performs the background correction for the uniform (default) and non-uniform spatial distribution. The background normalization is calculated on the base of shadowgrams from which the pixels affected by all sources listed in the brPif catalog more than defined by the brPifThreshold parameter were removed.

As output it produces 3 shadowgrams of larger dimensions: corrected expanded shadowgram and corresponding variance and efficiency shadowgrams. Method to be applied for the pixel value interpolation in dead zones is defined by the parameter method_int.

Table: ii_shadow_ubc parameters included into the main script.
Name Name Type Description
(in the main script) (executable)
ii_shadow_ubc
SCW1_BKG_I_method_cor method_cor integer Method to be applied for background removal

possible values: 0-2

0 - no background correction

1 - background from IC tree is applied to the whole detector

2 - background is treated for each module separately

default: 2

SCW1_BKG_I_method_int method_int integer Method to be applied for the pixel value interpolation

possible values:

0 - dead zone pixels will be filled with 0

1 - dead zone pixels will be filled with mean detector value

-1 - no dead zones

default:1

IBIS_NoisyDetMethod NoisyPixControl integer 0 = no Noisy Pixel detection; 1 = use SELECT_FLAG method.

default:0

brSrcDOL brPif string DOL of the bright sources catalogue, which will be removed from background mean calculation

default `` ''

SCW1_BKG_I_brPifThreshold brPifThreshold real pixels with PIF value higher will be removed from background calculation.

When = 1, bright PIF removal will not be performed

possible values: ``0 - 1 ''

default: ``0.0001''

ModPixShad ModPixShad integer Minimum number of non-illuminated pixels per module

possible values: 100 - 500

default:400
