The targets were observed at least once a month, with higher cadences of 2-4 measurements per week for circumpolar objects. Nearly 80 percent of the sources display variability greater than 10 per cent on a time-scale between a week and a few years but about three quarters of the sample have only 1-3 spectral features which vary significantly. Irregular intensity fluctuation is the dominant type of variability and only nine objects show evidence ","authors_text":"Anna Bartkiewicz, Marian Szymczak, Mateusz Olech, Pawe{\\l} Wolak, Rafa{\\l} Sarniak","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-10-12T16:24:25Z","title":"Monitoring observations of 6.7 GHz methanol masers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.04595","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a0e2cad7d7f3a2c661e1450829cc927c08110f820d912ca1d4238c8a64bf009a","target":"record","created_at":"2026-05-18T00:27:42Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"35b4245e46a36f54a863d32ab2d2fe3217d472c5bd18d1de26dc67e3860e0a18","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-10-12T16:24:25Z","title_canon_sha256":"d0ae3c3a5b6d0afad38ff0a57a6d747cdfc7bd44858b8b350a2606524fd55272"},"schema_version":"1.0","source":{"id":"1710.04595","kind":"arxiv","version":1}},"canonical_sha256":"6d18b2c9c6a7c0acb8b7638c92f8056cd3740bda7f2397c62fed8b5c026e0727","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6d18b2c9c6a7c0acb8b7638c92f8056cd3740bda7f2397c62fed8b5c026e0727","first_computed_at":"2026-05-18T00:27:42.732049Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:42.732049Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"US0TZcJPFfIh1fSJnSz0i5vh2iMfNknntC0AXqGt+o+tmve5lkhPTkiaLjOjH201IXmqlXcNQkJzuov8G5WyAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:42.732693Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.04595","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a0e2cad7d7f3a2c661e1450829cc927c08110f820d912ca1d4238c8a64bf009a","sha256:6fb68885b09c247f27125de7e9f3128be7404412ca2a5f1de2577daffeee1a30"],"state_sha256":"e386ca9c8d13a8afcac73fe508b3133dc1f0d2b12b10d8efdcc917cf1f7dd403"}
