Petr Kubanek
2010 arXiv   pre-print
This work was inspired by author experiences with a telescope scheduling. Author long time goal is to develop and further extend software for an autonomous observatory. The software shall provide users with all the facilities they need to take scientific images of the night sky, cooperate with other autonomous observatories, and possibly more. This works shows how genetic algorithm can be used for scheduling of a single observatory, as well as network of observatories.

RTS2—The Remote Telescope System

Petr Kubánek
2010 Advances in Astronomy  
RTS2is an open source observatory manager. It was written from scratch in the C++ language, with portability and modularity in mind. Its driving requirements originated from quick follow-ups ofGamma Ray Bursts. After some years of development it is now used to carry tasks it was originally not intended to carry. This article presents the current development status of theRTS2code. It focuses on describing strategies which worked as well as things which failed to deliver expected results.

2008 Advanced Software and Control for Astronomy II  
Remote Telescope System 2nd version (RTS2) is an open source project aimed at developing a software environment to control a fully robotic observatory. RTS2 consists of various components, which communicate via an ASCII based protocol. As the protocol was from the beginning designed as an observatory control system, it provides some unique features, which are hard to find in the other communication systems. These features include advanced synchronisation mechanisms and strategies for setting

It also assesses protocol performance, and provides examples how the RTS2 library can be used to quickly build an observatory control system. From the early beginning RTS2 was designed as a plug-and-play system, capable to drive various instruments and to provide a common infrastructure for them. It is clear that this component system needs some communication layer. Initial investigation of the off-the-shelf communication libraries led to decision to develop an own layer on top of the TCP/IP protocol stack. After years of development this communication layer matured to a level that it easily supports requirements from new instruments and experiments. Due to its focus on observatory control it can be considered to be better observatory communication library then the off-the-shelf libraries available today. Articles describing a complete observatory software environment are very rare. This paper tries to fill the gap by providing the description of a software environment for the complete control of the autonomous observatory operations.

2012 arXiv   pre-print
We report on multicolor photometry of long GRB080603B afterglow from BOOTES-1B and BOOTES-2. The optical afterglow has already been reported to present a break in the optical lightcurve at 0.12+/-0.2 days after the trigger. We construct the lightcurve and the spectral energy distribution and discuss the nature of the afterglow.

Precision stellar photometry using a telescope equipped with a CCD camera is an obvious way to measure the total aerosol content of the atmosphere as the apparent brightness of every star is affected by scattering. Achieving high precision in the vertical aerosol optical depth (at the level of 0.01) presents a series of interesting challenges. Using 3.5 years of data taken by the FRAM instrument at the Pierre Auger Observatory, we have developed a set of methods and tools to overcome most of

The main issues for data processing include camera calibration, source identification in curved field, catalog deficiencies, automated aperture photometry in rich fields with lens distortion and corrections for star color. In the next step, we model the airmass-dependence of the extinction and subtract the Rayleigh component of scattering, using laboratory measurements of spectral sensitivity of the device. In this contribution, we focus on the caveats and solutions found during the development of the methods, as well as several issues yet to be solved. Finally, future outlooks, such as the possibility for precision measurements of wavelength dependence of the extinction are discussed.

We describe the evolution of RTS2 from Python-based RTS to C and later C++ based RTS2, focusing on the problems we faced during development. The internal structure of RTS2, focusing on object layering, which is used to uniformly control various devices and provides uniform reporting layer, is also discussed.

Na našem pracovišti bylo nutné provést nové vyšetření pomocí jícnové echokardiografi e, které jasně dokumentovalo rupturu aneurysmatu nekoronárního Valsalvova sinu vyklenujícího se do pravé síně. Dopplerovsky byla ověřena komunikace mezi aneurysmatem a pravou síní. Aortální chlopeň byla bez stenózy s lehkou aortální insufi ciencí a byla potvrzena normální velikost kořene i ascendentní aorty. V descendentní aortě bylo detekováno pandiastolické obracení krevního proudu. Pravá komora měla kvůli objemovému přetížení hraniční velikost s normální systolickou funkcí. Při angiografi i bulbu aorty byl potvrzen echokardiografi cký nález a zobrazena komunikace mezi nekoronárním Valsalvovým sinem a pravou síní. Při pravostranné katetrizaci byla zjištěna středně těžká plicní hypertenze se středním tlakem v plicnici 33 mm Hg (53/20 mm Hg). Průtok zkratem byl 3,98 l/min s výsledným levopravým zkratem 1,9 : 1 (stanoveno oxymetricky s odhadovanou spotřebou kyslíku). Pacient byl indikován k chirurgickému řešení a byla mu provedena plastika defektu Valsalvova sinu spolu s plastikou (dekalcifi kací) aortální chlopně. Pro peroperační nález středně významné až významné mitrální regurgitace byl výkon doplněn současně o anuloplastiku mitrální chlopně. Pooperační průběh byl bez komplikací.

Scheduling in Targeted Transient Surveys and a New Telescope for CHASE

Francisco Förster, Nicolás López, José Maza, Petr Kubánek, G. Pignata
2010 Advances in Astronomy  
We present a method for scheduling observations in small field-of-view transient targeted surveys. The method is based on maximizing the probability of detection of transient events of a given type and age since occurrence; it requires knowledge of the time since the last observation for every observed field, the expected light curve of the event, and the expected rate of events in the fields where the search is performed. In order to test this scheduling strategy we use a modified version of

In particular, we present example schedules designed for a future 50 cm telescope that will expand the capabilities of the CHASE survey, which aims to detect young supernova events in nearby galaxies. We also include a brief description of the telescope and the status of the project, which is expected to enter a commissioning phase in 2010.

2012 Observatory Operations: Strategies, Processes, and Systems IV  
RTS2, or Remote Telescope System 2nd Version, is an open-source, distributed and modular observatory control system. During the course of its development lasting over a decade, the original goal to develop software capable of searches for optical transients of γ-ray bursts changed to develop a system for full control of large observatories executing complex observing scenarios. In this presentation, we would like to share our experience with meta-queues scheduling, developed primarily for

Meta-queues scheduling allows observers to quickly build and combine different observational scenarios, while still retaining ToO and weather interruption capabilities. Thanks to the queues and scheduling graphical user interface, observers can use the system without the need to understand complex functions used in the traditional merit function scheduling. By combining meta-queues and merit function scheduling, observatories can offer different options to schedule their observations to their users, so the acquired data will match the observers' expectations.
