RTT150 project data archive
This page is a search interface through RTT150 observationsdatabase which is stored at IKI. According to the agreement between participantsof RTT150 project, observational data fully belong to the institution which hascarried out this observation for one year, are available to all three partiesinvolved (IKI, KSU and TUG) during the second year and become freely accessibleto the whole astronomical community starting two years after observation date.
Data archive consists of the files with raw observational and calibration data in FITS format which are stored on the hard drive of a special server at IKI RAS. Data on the disk are separated by directories named YYYY-MM(YYYY - year, MM - month) corresponding to the dates of observation. Links from the search systems are pointing to these directories. Observational data (FITS files) are stored within corresponding directories in compressed format. There can be two kinds of data:
1. All observations of a given night (including calibration data) are packed in one file. In this case it will have a name like yyyymmdd.zip where yyyy is theyear, mm - month, dd - day of observation. The date refers to the evening of observation night, that is, for example, data on the source that was observedon Aug. 31st, 2001 at 1h, should be looked for in the file 20010830.zip. After unpacking this file by the user directory yyyymmdd is created which contains FITS files within subdirectories whose names correspond to the source names ofcalibrations.
2. Observations of the night are broken into several zip files, each of them containing data on a specific source or one series of calibrations. The name of archive will then consist of observation date together with source name likeyyyymmdd.name.zip where name refers to the source or type of calibration data (bias, dark, flat/dome).
