Data-Format

After the parameters comes the actual variable star observations. There should be one observation per line and the fields should be separated by the same character that is defined in the DELIM parameter field. If you do not have data for one of the optional fields, you must put "na" as a place holder. The list of fields are:
    STARID: The star's identifier. It can be the AAVSO Designation, the AAVSO Name, or the AAVSO Unique Identifier, but NOT more than one of these. Limit: 30 characters.
    DATE: The date of the observation, in the format specified in the DATE parameter. Limit: 16 characters.
    MAGNITUDE: The magnitude of the observation. Prepend with < if a fainter-than.  A dot is required (e.g. "9.0" rather than "9"). Limit: 8 characters.
    MAGERR: Photometric uncertainty associated with the variable star magnitude. If not available put "na". Limit: 6 characters.
    FILTER: The filter used for the observation. This can be one of the following letters (in bold):
        U: Johnson U
        B: Johnson B
        V: Johnson V
        R: Cousins R (Rc = R)
        I: Cousins I (Ic = I)
        J: NIR 1.2 micron
        H: NIR 1.6 micron
        K: NIR 2.2 micron
        TG: Green Filter (or Tri-color green). This is commonly the "green-channel" in a DSLR or color CCD camera, or Astroimaging G filter. These observations use V-band comp star magnitudes.
        TB: Blue Filter (or Tri-color blue). This is commonly the "blue-channel" in a DSLR or color CCD camera, or Astroimaging B filter. These observations use B-band comp star magnitudes.
        TR: Red Filter (or Tri-color red). This is commonly the "red-channel" in a DSLR or color CCD camera, or Astroimaging R filter. These observations use R-band comp star magnitudes.
        CV: Clear (unfiltered) using V-band comp star magnitudes (this is more common than CR). A clear with blue-blocking (CBB) filter commonly used for exoplanet observations should be considered a CV filter. Report "CBB filter" in NOTES field.
        CR: Clear (unfiltered) using R-band comp star magnitudes. A clear with blue-blocking (CBB) filter commonly used for exoplanet observations should be considered a CR filter. Report "CBB filter" in NOTES field.
        SZ: Sloan z
        SU: Sloan u
        SG: Sloan g
        SR: Sloan r
        SI: Sloan i
        STU: Stromgren u
        STV: Stromgren v
        STB: Stromgren b
        STY: Stromgren y
        STHBW: Stromgren Hbw
        STHBN: Stromgren Hbn
        MA: Optec Wing A
        MB: Optec Wing B
        MI: Optec Wing C
        ZS: PanSTARRS z-short (APASS)
        Y: PanSTARRS y (APASS)
        HA: H-alpha
        HAC: H-alpha continuum
        O: Other filter not listed above, must be described in NOTES. Please Note: Due to a problem in WebObs, this filter choice is currently unavailable. Please consider removing your filter and using CV or TB/TG/TR instead.
    TRANS: YES if transformed using the Landolt Standards or those fields that contain secondary standards, or NO if not. Document the method used to transform in the "NOTES" section.
    MTYPE: Magnitude type. STD if standardized (Click here for definition of standardized) or DIF if differential (very rare). If you are currently using ABS for 'absolute' we will still accept it. Differential requires the use of CNAME.
    CNAME: Comparison star name or label such as the AUID (much preferred) or the chart label for the comparison star used. If not present, use "na". Limit: 20 characters.
    CMAG: Instrumental magnitude of the comparison star. If "ensemble" see example below. If not present, use "na". Limit: 8 characters.
    KNAME: Check star name or label such as the AUID (much preferred) or the chart label for the check star. If not present, use "na". Limit: 20 characters.
    KMAG: Instrumental magnitude of the check star. If "ensemble" see example below. If not present, use "na".Limit: 8 characters.
    AIRMASS: Airmass of observation Limit 7 characters - entry will be truncated if longer than that. If not present, use "na".
    GROUP: Grouping identifier (maximum 5 characters). It is used for grouping multiple observations together, usually an observation set that was taken through multiple filters. It makes it easier to retrieve all magnitudes from a given set in the database, say, if someone wanted to form color indices such as (B-V) with them. If you are just doing time series, or using the same filter for multiple stars, etc., just set GROUP to "na." For cases where you want to group observations, GROUP should be an integer, identical for all observations in a group, and unique for a given observer for a given star on a given Julian Date. Limit: 5 characters.
    CHART: Please use the sequence ID you will find written in Bold print near the top of the photometry table in a sentence that reads "Report this sequence as [ID] in the chart field of your observation report." If you used your own comparison stars (e.g. in the case of time-sensitive alerts when the Sequence Team had no time to create a sequence), do not give a chart ID, even if you plotted the chart using VSP. Use the comment code K (non-AAVSO chart) and give a proper chart name like "APASS DR10". Then add information on the comp stars in the notes. Limit: 20 characters.
    NOTES: Comments or notes about the observation. If no comments, use "na". This field has a maximum length of several thousand characters, so you can be as descriptive as necessary.  The convention to use for including a lot of information as concisely as possible is to use subfields after any freeform comment you wish to make. The subfield format is |A=B; the '|' character is the separator, A is a keyword name and B is its value. To make it possible to programatically access this information, use keywords taken from this list:
        VMAGINS, CMAGINS, KMAGINS are the instrumental magnitudes of target, single comp, and check star
        CREFMAG and KREFMAG are the reference magnitudes of comp and check
        CREFERR and KREFERR are the errors of the reference magnitudes
        VX, CX and KX are the airmass values for target, comp and check
        Transform coefficients can also be documented here. See the example below

        Not all the values are necessary. But using this mechanism you can document your submission in much better detail. Here is an example of a notes field created by TransformApplier:

        (free format notes)|NOBS=5|VMAGINS=-7.244|VERR=0.006|CREFMAG=13.793|CREFERR=0.026| KREFMAG=14.448|KREFERR=0.021|VX=1.1501|CX=1.1505|KX=1.1500|Tv_bv=0.0090|Tv_bvErr=0.0100| TAver=2.47
