121 Summary:
122 Specify the names of the data files and MeasurementSet
124 Description:
127 This function does the actual filling of the data from rpfits format
128 files to a MeasurementSet. After the completion of the fill operation
129 you should call the done method to avoid problems with incomplete
130 flushing of the data to disk. You may want to run select before fill, to
131 reduce the amount of data you read in.
133 In the filenames argument commas are not allowed because of the
134 wildcard capability.
136 The options argument allows for special processing options during the
137 filling process.
139 * birdie: remove self generated birdies in 128 MHz
140 data by deleting every other channel and the edge
141 channels
142 * reweight: suppress ringing of interference spikes by
143 reweighting the lag spectrum for minimum spectral sidelobe response
144 * noxycorr: do not apply the xyphase
145 correction using the noise cal xy phase measurements (use if you
146 know there was a problem with the measurements)
147 * compress: Compress the data, model, corrected data and imaging weight
148 columns (may reduce dynamic range)
149 * fastmosaic: Produce a MeasurementSet with small tiles to optimize I/O
150 for observations with a large number of pointings and a short time (a few
151 integrations) on each pointing. Failing to use this options for such data
152 may cause very inefficient access, especially for continuum data
153 (10-100 times slower)
154 * hires: For data taken in binning mode: set the TIME_CENTROID column to
155 the center of each bin (normally center of integration interval). The TIME column is
156 unaffected. TIME_CENTROID will no longer be in time order for dual frequency
157 mode.
158 * noac : Do not load the autocorrelations
160 Input Parameters:
161 msname Filename for MeasurementSet to create
162 filenames Existing RPFITS files to read; wild cards accepted, don't use commas
163 options Processing options: birdie, rfiflag, noxycorr, compress, fastmosaic, hires, reweight, noac

230 Summary:
231 Select the data to fill
233 Description:
237 Select on various items, to load only a subset of the data present in
238 the input file. The default is to load everything.
239 Note that the frequency selection using lowfreq and highfreq acts purely on
240 center (reference) frequencies, channel selection is not available at this stage.
241 Use freqchain to select the frequency chain (or IF) to load,
242 specify either 1 or 2, the default of zero will load both.
243 Use the fields parameter to specify a list of field names (sources) you
244 want to load.
245 For detailed selection of complex observations the last two parameters let
246 you specify the required bandwidth (in whole MHz) and number of channels
247 of the first frequency chain.
249 Input Parameters:
250 firstscan First scan to read
251 lastscan Last scan to read
252 spw Select one or more spectralwindows , -1=all
253 lowfreq Lowest reference frequency to select
254 highfreq Highest reference frequency to select
255 fields List of field names (sources) to select
256 edge Percentage of edge channels to flag
258 Example:
260 #Select scans 4 to 10 inclusive, frequency chain 1, all data with a
261 #reference frequency of more than 1.4 GHz.
