3. Standard (Johnson) Magnitudes and Colours
... Standard magnitudes can only be computed for the U, B and V filters and hence the only standard colours that can be calculated are U-B, B-V and U-V. An important point to note, is that these standard colours can be computed using the following instrumental colours - U-B, B-V, U-V, (UVW1-U), (UVW1-B), (UVW1-V), (UVW2-B) and (UVW2-V). ... The program loops through these colours and if the relevant instrumental magnitudes are present computes the standard magnitudes and standard colour. ...

4. Standard stars
Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...

11. STANDARDS OF REST & REDSHIFT CORRECTIONS
Next: THE SOURCE LIST Up: Spectral-Line Observing at AO Previous: THE RADAR BLANKER . ... You also need to decide how you want this correction to be applied - to the center of each correlator board or to the four boards as a whole (thereby preserving the topocentric frequency offset between the boards). Typically, this choice depends on whether each board is centered on a known spectral line, or if you are doing a search in velocity space for an object. ...

15. Redirecting standard input
. To redirect the standard input for a command use the < (less than) character followed by the name of the input file. For example: mail tony < memo . This redirects the standard input to the mail command so that it comes from the file memo . The effect of this is to mail the contents of this file to the user tony .
