-----------------------------

identical to 2.8.1 which for some reason was not
ingested into the system properly

Version 2.8.1 (2002-02-27) HB
-----------------------------

Closed SPR:
-SSC-SPR-2718: INSR array out of range if input source table empty (on Linux)

------------------------

the dynamic range of the input data for the spline fit was
compressed to avoid oscillations of the spline map in the
presence of bright extended sources

Closed SPR
+ SSC-SPR-2477 (on emldetect) fixed by extending the backgrounnd
to areas outside the FOV (if withexpimage=true)

Version 2.4 (2001-03-30)
------------------------

DEPEND file updated

Version 2.3.1 (2001-03-16)
--------------------------

Task parameter idinst was removed. The instrument id is now read
from the INSTRUME keyword of the input image.

+ SSC-SPR-2131 does not trap detmask from wrong camera
+ SSC-SPR-2251 float to string problem

Version 2.3 (2001-01-26)
------------------------

+ as suggested by JO, source cut-out radii are now source count dependent
(two new parameters, IDINST and IDBAND added. Parameter scut redefined)
+ SSC-SPR-2191 (was closed in v2.2): additional correction of number of
free parameters of spline fit: was (nx-4)(ny-4); corrected
to (nx-8)(ny-8) (= number of internal nodes of bicubic
spline fit; see, e.g., description of NAG routine E02DAF)
+ SSC-SPR-2056 on edetect_chain (already closed): additional measures
to reduce undesired oscillating behaviour of spline fit:
1. lower limit of background map forced to 20% value of
background histogram
2. removal of negative 4-sigma excesses from spline fit
input data (previously only positive 4 sigma excesses
were removed)

Version 2.2 (2001-01-15)
------------------------

Closed SPR:

+ SSC-SPR-2191 reduced chisqr quoted in output file keyword is incorrect.
The number of dof of the spline fit is now listedin
keyword NDOF.

------------------------

Closed SPRs:

- task now reads i1, i2, i4, r4, and r8 input images
- task description adjusted to actual functionality of
present task version
