t_starfocus.x
starfocus.par
psfmeasure.par
starfocus.hlp
psfmeasure.hlp
Added a "wcs" parameter to allow specifying the coordinate system type
for cursor input. (10/7/98, Valdes)
stfprofile.x
The logic in STF_FIT for determining the points to fit and the point
to use for the initial width estimate was faulty allowing some bad
cases to get through. (7/31/98, Valdes)
t_starfocus.x
There was an error in the changes to allow focus sequences to go
up or down such that simple PSF measurement failed.
(6/11/97, Valdes)
stfmeasure.x
stfprofile.x
Changes were need to better deal with error conditions.
(6/11/97, Valdes)
stfmeasure.x
Changes to deal with error conditions.
(6/11/97, Valdes)
t_starfocus.x
Fixed a typo error in an earlier change which left out the pointer
variable in a macro. (5/8/97, Valdes)
t_starfocus.x
1. Added a minimum radius of 3 to the input and to interative setting.
2. The estimate for the next focus position is not based on the previous
center plus the step.
3. Added commented out code to allow setting the selected star to always
be the top or bottom, etc.
(2/7/97, Valdes)
stfprofile.x
1. Added a minimum radius of 3 to stf_find.
2. Added a error return if sum2 <= 0 in stf_find
3. Added errchks in stf_widths for called procedures.
4. Added error returns in stf_fit for bad profile or parameters.
(2/6/97, Valdes)
t_starfocus.x
The parabola fitting routine would fail if the independent variable
(the focus values) became too large because a) use of real and b)
unscaled variables. The routine was revised for both these problems.
(10/24/96, Valdes)
stfprofile.x
stfmeasure.x
Fixed bug in evaluation of enclosed flux profile in which the scaled
radius was used for the gaussian subtraction stage instead of pixels.
This does not currently affect IMEXAM because the scale is fixed
at 1. (8/29/96, Valdes)
stfmeasure.x
stfprofile.x
Fixed incorrect datatype declaration "real np" -> "int np" in various
related places. (4/9/96, Valdes)
stfmeasure.x -
1. Restricted the peak pixel to be within the specified radius.
2. Renamed file and procedures to avoid library conflict.
(3/14/96, Valdes)
stfprofile.x
Minor bug fix that does not affect anything. (3/14/96, Valdes)
kpnofocus.cl
starfocus.par
psfmeasure.par
Changed the defaults for radius=5, sbuffer=5, swidth=5 to try and make
IMEXAMINE and the PSF tasks measure the same thing by default.
(3/13/96, Valdes)
stfprofile.x
Changed the centering routine to only use the data in the specified
radius rather than the extended region including the sky. (11/7/95, Valdes)
stfmeasure.x
mkpkg
Added a routine which can be called separately to compute the
enclosed flux width or radius and the direct FWHM. (11/6/95, Valdes)
stfprofile.x
starfocus.h
Added a computation of the direct FWHM. (11/6/95, Valdes)
t_starfocus.x
Make a change to avoid reloading the image display when the specified
image name and the image name in the display are same apart from
the image extension. (6/26/95, Valdes)
stfprofile.h
t_starfocus.x
stfprofile.x
starfocus.par
psfmeasure.par
kpnofocus.cl
starfocus.par
psfmeasure.par
kpnofocus.cl
Added saturation and ignore_sat parameters to allow flagging measurements
with saturated pixels and either ignoring them or including them but
showing them in the output log. (10/28/94, Valdes)
t_starfocus.x
Fixed bug in interpreting the focus parameter. (9/15/94, Valdes)
starfocus.h
t_starfocus.x
stfprofile.x
stfgraph.x
psfmeasure.par
starfocus.par
kpnofocus.cl
psfmeasure.hlp
starfocus.hlp
kpnofocus.hlp
Added an "iteration" parameter that, if greater than 1, uses the
previous FWHM estimate to adjust the "radius" parameter. (8/5/94, Valdes)
psfmeasure.hlp
starfocus.hlp
Clarified the description of the imagecur parameter. (2/1/94, Valdes)
t_starfocus.x
starfocus.h
starfocus.par
psfmeasure.par
kpnofocus.cl +
starfocus.hlp
psfmeasure.hlp
kpnofocus.hlp
1. A new parameter, fstep, was added to STARFOCUS to allow specifying
the focus sequence as a starting value, by the focus parameters,
and a step.
2. STARFOCUS was modified to allow specification of header keywords
for the focus (this was true previously), the focus step,
the number of exposures, and the multiple exposure shift.
This allows multiple exposure images to be completely header
drivien if the appropriate keywords are present.
3. A new task KPNOFOCUS was added. This is a script calling
STARFOCUS with parameters set specifically for Kitt Peak
headers containing the focus parameters in the header.
Many of the parameters are fixed in the script and the task
parameters are then simpler.
4. STARFOCUS/PSFMEASURE were modified to search all display frames
for the requested image rather than just frame 1.
5. A new parameters, frame, was added to STARFOCUS/PSFMEASURE
to specify the display frame to load if necessary. Previously
it was always frame 1.
7. In STARFOCUS the default number of steps was changed to 7 and
the default step size to 30.
