... Standard-star files, however, must also have the standard photometric values (in place of the rough MAG column). The column label should be the usual name of the magnitude or index in the column, e.g., V or U-B or c1; see Table . ... MIDAS table files do not distinguish between upper and lower case in column labels. Thus, while it is possible to use 'u-b' as a column label for the uvby system, it cannot be distinguished from 'U-B' by programs or MIDAS procedures that read these files. ...

The following spectra were obtained between 1997 and 1999; they are all flux calibrated and generally span the wavelength range 6000-10,000 A. Spectral types are on the Kirkpatrick et al system as defined in Kirkpatrick et al ApJS, 77, 417 (1991 - for M dwarfs) and Kirkpatrick et al ApJ 519, 802 (1999 - L dwarfs). While not all of these stars are primary spectral standards, they are all bright and should provide an adequate reference sequence. ... LHS 320 ,sdM2, red spectrum . ...

... 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). Omsrclistcomb computes all possible standard magnitudes for each of the U, B and V filters and displays them in a vector column. ...

... New IRAF tools for the photometric calibration of optical/IR images are presented. The new tools are standard star catalog and world coordinate driven, requiring both accurate standard star catalog coordinate and accurate image coordinate data. Network access to standard star catalog servers is supported. ... The photometric calibration software will automatically convert the standard star coordinates from the standard star coordinate system to the image coordinate system. ...

. To append the standard output from a command to a file use two >> (greater than) symbols followed by the name of the file. If the file does not exist it is created. For example: cat part1 > chapt2 cat part2 >> chapt2 . This creates a file called chapt2 with the same contents as part1 . It then reads the contents of part2 and appends them to the file chapt2 . The file chapt2 now contains the data from part1 followed by the data from part2 .
