The first tab defines the targets to be observed. Only the targets from the
proposal are allowed, except for special cases of targets approved by the SOD
(Sect. 3.3). In the first column - Code - one should place an
identifier that will later serve as a reference to this particular target. In the targets tab as well as the subsequent tabs, only alphanumeric characters [0-9a-zA-Z] and the underscore symbol “_” and period symbol “.” are allowed in the Code field. This applies to all Code fields. For checking and validation purposes, QWG will fill the Target Name and the RA, DEC fields with the target names and coordinates, which will be write-protected, based on the information in the proposal. If there is need to shift the pointing centers, one needs to define these as new targets below the pre-filled lines. In this case, one needs to place a new object in the Code and Target Name fields, and new pointing center coordinates in the RA, DEC fields. The format hh:mm:ss.ss and ()dd:mm:ss.ss must be used, respectively, but with the note that Google spreadsheets do not accept strings starting with the hyphen character “-”. Such strings as, e.g., negative declination, should be preceded with a single hyphen (“ ' ”). The entries in Target Name, here and in subsequent tabs,
may contain blank spaces (e.g. "My first target"). The Target Name will be the name saved later in the OBJECT keyword of the FITS file header.
The Equinox should be set in the next column.
If observations of one or more custom standard star fields are desired, they should be defined as a new targets
(new lines), and specified in the calib_target fields in the ob tab. The custom standard star fields can be SDSS fields, in case the science target is outside of the SDSS coverage; 30 second exposures of SDSS fields are taken as part of the normal calibration set, and the field will be used for photometric calibration, IQA and environmental
(observing) constraints check. In addition, custom fields outside SDSS can be specified; this is frequently the case for narrow-band observations.
Note that starting from S18B, the observatory observes spectrophotometric standard stars in narrow-band filters, which will not be charged to the PIs. However, if the PI wishes to obtain a specific calibration target, this can be specified as described above, but the time will be charged to the PI.
