20.18. HOW TO SAVE SPOILED OBSERVATIONS 269 20.18 How to save spoiled observations The data of some observations are spoil and therefore resists standard CIA data reduction. The most common reasons are: 1. telemetry drops 2. bad raster point IDs 3. target not acquired 4. bad QLA flag 5. bad CSH flag 6. strong saturation CIA provides the functionality to recover some of these observations. However, only experienced CIA users should try these steps! telemetry drops Short telemetry drops, affecting only a few readouts, will normally go unnoticed. For longer telemetry drops, were the data for one or more SCDs is missing, the following actions can be taken: • raster observations: Calling get sscdraster with the option /nocheck will permit you to continue with the data reduction. CIA> raster_pds = get_sscdraster(sscd, /nocheck) Alternatively, sscd clean will fake empty SCDs so that get sscdraster is tricked into believing the raster is complete. CIA> cleaned_sscd = sscdclean(sscd) CIA> raster_pds = get_sscdraster(cleaned_sscd, /nocheck) • CVF observations: CIA data reduction is not affected by telemetry drops. • Beam-Switch observations: With most beam-switch observations consisting only of one on and one off-position, the observation is quite likely lost. If there are more on/off positions, use get sscdstruct on the “cleaned” dataset, e.g. a dataset containing no spurious SCDs any more, and combine the results of on/off positions manually. • Polarization observations: It will depend on the redundancy of the observation, whether the observation is lost. If there are sufficient observations with all polarizors, use get sscdstruct on the “cleaned” dataset, and combine the results manually. badrasterpointIDsSome observations are affected by an invalid [0,0] raster-point ID. sscd clean will remove these SCDs so you can progress with your data reduction. However, the final mosaic will contain holes — in the example below 39 readouts for the three pointings with the raster-point IDs [26,2], [25,2] and [24,2] are merged in one SCD, SCD #35.
