Brief description of  Work Scan

Main functions of processing, realized in the program are:

 


Header of FITS file for RATAN solar observations

SIMPLE = T /
BITPIX = 16 /
NAXIS = 0 /
EXTEND = T /
COMMENT This table contains the set (TFIELDS) of 1-dimensional (TFORM#
COMMENT and TDIM#) full disk scans of the Sun at microwaves (TTYPE#)
COMMENT obtained with the RATAN-600 radio telescope. The fan beam
COMMENT observations are made daily in transit mode near the local noon
COMMENT (i.e. at about 9 UT). Both R-handed and L-handed circular
COMMENT polarizations are registered. The time in the DATE_OBS is the
COMMENT calculated UT time of the transit of the solar disk center through
COMMENT the local meridian. A small deviation of antenna beam position
COMMENT from local meridian and also the difference dUT1 are not
COMMENT accurately corrected. About 40 frequency channels in the range from
COMMENT 1.0 GHz to 18 GHz (i.e. at wavelength 30 to 1.6 cm)
COMMENT are used simultaneously. The beam size is frequency dependent.
COMMENT The horizontal HPBW is approx. 225/OBS_FREQ_GHZ ARCSEC.
COMMENT The vertical HPBW is approx. 127/OBS_FREQ_GHZ ARCMIN.
COMMENT If you will have any problems with this FITS-format please write
COMMENT to Solar Group. E-mail sun_a_ratan.sao.ru
HISTORY This FITS file was created by the 'Work Scan' task.
