The plotting of a Pan-STARRS light curve from the Internet is similar to the plotting of an ASAS-3 or ZTF light curve, both of which are explained in detail in this User Guide.  


The Plot light curve from Pan-STARRS1 DR2 dialog box consists of two sections: the upper one is labeled Star name, and allows to enter the AAVSO VSX name or SIMBAD name of the star to be plotted, or its (J2000.0) RA and Decl coordinates. Both values have to be separated with a semi-colon. RA and Decl need to be in sexagesimal format with values separated by spaces. So, a valid entry would be: 04 59 13.57; -69 35 43.3. Or its (J2000.0) RA and Decl coordinates, expressed in degrees and separated with a semi-colon. Example: 76.80654; -69.595361.


The fields in the Additional fields section are identical to the ones found in the ASAS-3 and ZTF descriptions, except for:


    • 5 filter bands: Pan-STARRS observations are made in the g, r, i, z and y bands. The thick boxes allow to select if you want to retrieve g-band, r-band, i-band, z-band or y-band observations, or any combination. All observations belonging to the same band will be grouped in one Observation set. 

      Peranso by default colors g-band observations in green, r-band observations in red, i-band observations in fuchsia, z-band observations in blue and y-band observations in black.


    • Observations quality requirement: each observation in the Pan-STARRS data release has a quality indicator number, ranging from 1 (extremely low quality photometry) to 100 (excellent quality photometry). Using this field, you can reject observations that fail the quality requirement. For instance, specifying a value of 75 will reject all observations having a quality indicator number below 75. Using a higher number will result in more rejected observations. Peranso displays them as inactive observations, ensuring that they will be excluded from period analysis calculations. We recommend to use a value of 75 or more.


If multiple objects match the search criteria, Peranso will ask you to select one, from the list of (unique) Pan-STARRS1 object identifiers of each matching object. 


The magnitude of the observations in a Pan-STARRS1 DR2 ObsWin are PSF magnitudes calculated from the flux value of the corresponding filter.
