Target List

Target list (ASCII) with the format specified below will be provided (ftp, see below).
This is recommended for larger lists.

Priority:
No priority, look always for best RA
Target list order indicates strict priority. Go to next object, when the previous one is done (if possible).
Target list order indicates priority. Go to next object, when airmass would be higher than at start of exposure


Target List
  • Use | as separator between entries
  • RA: enter in hh:mm:ss.s format
  • DEC: enter in sdd:mm:ss.s format
  • Time: Enter
    • fixed observing time (sec) (Format: sxxx, default)
    • OR desired S/N in continuum (Format: nxxx)
    • OR desired electrons in maximum (Format: exxx)
      (Example: n80 means an exposure with a signal/noise ratio of 80 for the specified object).
  • Rep's: Enter number of repetitions.
  • Remarks: For long remarks number them and write them into 'General Comments'



Finding charts are supplied on the anonymous ftp-Server of Calar Alto (ftp.caha.es: CApub/teles/incoming/"PI-Name")



Calibrations required:
Biases
Sky Flatfields
Dome Flatfields (Screen)
Internal Flatfields
Wavelength Calibration Spectra Ne He/A Fe/Ne Th/A
Flux Standards
Others:



Data transfer:
I shall copy the data via ftp; I'll be notified of the directory.
Send me the data on DAT: single FITS-files
Send me the data on DAT: tar-file(s)
Calar Alto will keep the data at least 2 weeks on disk. Before deleting them a security copy will be made which remains on Calar Alto.
