I'm the astronomer.
I am interesing in optical variability of the Active galactic nuclei,
especially blazars and their connection
to gamma-ray bursts. I computed a light curve of optical afterglow.
I am working in field of advanced methods for the processing of
astronomical images. I works in INTEGRAL team.
I cooperate with
Rene Hudec.

I have been interested in following problems during last years:
- Meteors.
- My diploma research was done on field of statistical
methods of determining radiant of meteor streams using the
method known as 'Probability Distribution Function'
from RADIANT code by R. Arlt.
Display map.
- KW method.
- I have coded Kwee-Woerden method for evaluating
time of minima of eclipsing binary stars. The package
is available here. I have also
main and dataset
with gaussian noise N(0,0.1) for function y = 1 + |x|,
description in Czech and
old Pascal sources in great chaos.
- CCD photometry.
- I work with DAOPHOT and ROMAFOT procedures for
crowded fields stellar photometry. I have coded
package MUNIPHOT for aperture photometry of our CCD frames.
More information about MUNIPHOT (in Czech)
is here and
here in English.
- Matching algorithms.
- I have coded a MUNIMAT program for finding cross-
references between CCD frames or stellar
catalogue and CCD frames. MUNIMAT package
description and source code links are available
here.
- Munipack
-
I have developed the simple package for the time series
photometry. This package Munipack is available for UNIX user at
my
office computer (sources + docs + binaries). See also
Munipack Home page.
- Utilites for CCD frames reduction.
- The another link to this utilites is
here.
- Midas.
- I use
MIDAS
package from
ESO for reducing our CCD
frames.
Example: I made astrometry of the comet 1996B2 (Hyakutake)
with my friends from Brno
here.
- Nova Cygni 1992.
- I have observed it with my friends D. Hanzl and E. Safarova-Neureiterova.
See IAU Circ. No.
5520 and
5537.
- FITS.
- FITS is a flexible image transport system.
Description can be found in : Wells et al.:
Astron. Astrophys.Suppl.Ser. 44,363-370, (1981).
