Key words and links

MAP ID# is an identification number for a single map. It indicates the radiotelescope (Medicina or SRT), the observation date (expressed as YYMMDD) and the order in which the map were acquired during the day (_1 indicates the first map acquired, _2 indicates the second, and so on). Here an example of MAP ID: MED_191114_1 indicates the first map acquired during the observation on the date 14/11/2019 with the Medicina radiotelescope.

EPOCH indicates the observation date expressed as DD/MM/YYYY. 

TIME INTERVAL (UT)  illustrates the acquisition time interval of the map. The time is expressed as Universal Time.

CENTRAL FREQ (GHz) is an abbreviation for central observation frequency. 

IMAGE (PNG) is a link to a representative map image in PNG format. 

FLAGS consists of a series series of abbreviation, acronyms or words that indicate specific characteristics of the corresponding  map: 

• 1. T or S (Test or Science) indicates whether the map was acquired during a test session or in the contest of a science observation. In case the session contains both test and science observation, the flag in written as T/S;

  2. CA (Cas A). We utilize this flag in the case the Supernova Remnant CasA was observed during the session for calibration purposes;

  3. DF (Dual Frequency) flag is present when the Sun was observed at two different central frequency during the same observing session. If  the Sun was observed at more than two different central frequency during the same observing session, the flag is MF (Multiple Frequencies);

  4. AR (Active Region) points out the presence of one or more Active Region in the map. For now, we identify Active Regions as approximately punctiform bright spots that stand out from the surrounding quiet region.

  5. Flags HQ, MQ or LQ give a qualitative interpretation of the final image. In general, with Low Quality (in red colour) we indicate a map image with numerous and clear artefacts (due to RFI and/or poor sky opacity conditions). When the artefacts are only a few and not remarkable we use the Medium Quality flag (in orange colour). Finally, when the image is clear or the artefacts are negligible, we assign the Quality as High (in green colour);

  6. C indicates that standard Calibrators different from CasA were observed during the session;  

  7. CS is a flag used when the session Sun includes Cross Scan observations (see Loru S., Pellizzoni A., Egron E., "Investigating the high-frequency spectral features of SNRs Tycho, W44, and IC443 with the Sardinia Radio Telescope" for more detail on this technique);

  8. RA/DEC is the scan direction: Right ascension or Declination;

  9. V# specifies the Pipeline Version used in order to analyze the raw data;

  10. TP/SD/SK indicates the backend in use: Total Power, SARDARA or SKARAB.

IMAGES (DS9 FITS) is a link to the DS9 fits files obtained after the analysis.

The link RAW DATA brings to the raw data of the observing session.

OBS.REPORT is a link to a report of the observing session. The reports contains details about the weather, set up parameters and others.

NOTES (work in progress): it will include details on solar features detected during the observations.
