| 53 | | [http://www.atnf.csiro.au/computing/software/miriad/doc/atlod.html atlod] does a qualitatively different type of |
| 54 | | flagging to other parts of Miriad; it drops data from the output instead of just marking it as bad. |
| 55 | | There are two possible types of flagging-related changes. |
| 56 | | * basic things like removal of [wiki:Glossary/Birdies birdies] - there are likely to be some new ones.[[BR]] |
| 57 | | Research needed: locations of birdies; will there be new types of flags on scans that indicate bad data? |
| 58 | | * Possibly using the [Glossary/AutoCorrelations autocorrelations] to flag data affected by interference. |
| | 53 | [http://www.atnf.csiro.au/computing/software/miriad/doc/atlod.html atlod] does not copy bad data to its output. |
| | 54 | This makes flagging in ATLOD qualitatively different to other parts of Miriad. Other editing tasks in Miriad |
| | 55 | set flags in a flag table to mask out bad data. |
| | 56 | |
| | 57 | For CABB data, ATLOD's [wiki:Glossary/Birdies birdie] flagging will change: |
| | 58 | * a different set of birdie frequencies (to be determined) |
| | 59 | * removal of every second frequency channel will not be needed. |
| | 60 | |
| | 61 | Research needed |
| | 62 | * What are the birdie frequencies in the new system? |
| | 63 | * Can data be flagged automatically by ATLOD using [Glossary/AutoCorrelations autocorrelations]? |
